As someone who is often on SF city streets without a car - I bike and run a lot - I absolutely love Waymo. I am continuously seeing human drivers cut me off, perform illegal maneuvers (i.e. run red lights when I'm going through a crosswalk), and break various other traffic laws. All these things genuinely put people in danger. Just the other day, a guy started running a "no right turn on red" lane in SF, and when I pointed it out to him he floored his car - through the red - right in front of me and laughed at me as he sped away. To say nothing of all the times when cars will honk or give me the finger for doing normal things on a street, like walking on a crosswalk.
Waymo is like the most courteous, respectful driver you can possibly imagine. They have infinite patience and will always take the option which is the safest for everyone. One thing which really impressed me is how patient they are at crosswalks. When I'm jogging, a Waymo will happily wait for me to cross - even when I'm 10 feet away from even entering the crosswalk! I don't know if I even have that much patience while driving! I've had a number of near misses with human drivers who don't bother checking or accelerate for no reason after I'm already in the crosswalk. Can you imagine a Waymo ever doing that?
If I see a Waymo on the street near me I immediately feel safer because I know it is not about to commit some unhinged behavior. I cannot say enough good things about them.

The one time I ever rode in a waymo (in Los Angeles), I had a contradictory experience. My Waymo was attempting to make a right turn at a red light. We were stopped behind a human driver who was waiting for pedestrians to finish crossing before proceeding to make the turn. This was a college campus (UCLA), so there were lots of pedestrians. After a few seconds of waiting, the Waymo decided that the driver ahead of us was an immobile obstacle, and cut left around this car to complete the right turn in front of it. There was only one lane to turn into.
Luckily, no one was hurt, and I generally trust a waymo not to plow into a pedestrian when it makes a maneuver like that. I also understand the argument that autonomous vehicles are easily safer on average than human drivers, and that’s what matters when making policy decisions.
But they are not perfect, and when they make mistakes, they tend to be particularly egregious.
GavinMcG · 35m ago
That mistake might induce human error—which is absolutely a source of danger—but it undoubtedly had a clear path to pull around the “stopped” vehicle, and as you said, you can generally trust Wayno not to plow into pedestrians. So what made it “lucky” that no one was hurt?

Fellow SF cyclist:
Even setting aside the malicious SF stuff, Waymo's have enormous advantages over humans relying on mirrors and accounting for blindspots. I never have to be concerned a Waymo hasn't seen me.
I can't wait until the technology is just standard on cars, and they won't let drivers side-swipe or door cyclists.

Funnily enough that's exactly why I don't like them. Every time one rolls by me I know that tens of photos of me and even my 3D LIDAR scan get piled in to some fucking Google dataset where it will live forever :/
“The Waymo Driver's perception system takes complex data gathered from its advanced suite of car sensors, and deciphers what's around it using AI - from pedestrians to cyclists, vehicles to construction, and more. The Waymo Driver also responds to signs and signals, like traffic light colors and temporary stop signs.”
kajecounterhack · 12h ago
Totally fair to be concerned about pervasive surveillance for the _potential_ of privacy violation. Not sure what to do about that.
That being said, just speaking with some knowledge of current state: the scans don't live forever. At this point, all the data they collect is way too big to store even for a short period. They'll only keep data in scenarios that are helpful for improving driving performance, which is a tiny subset.
Personally identifiable information is also redacted.
You should probably be more worried about what gmail knows about you than Waymo.
Lammy · 12h ago
True; I should have said metadata and not just data since you're right that the volume of raw images would be too big to store indefinitely. It's way more feasible to process the raw images and store the inferences, like number of persons visible in last 5 seconds, or dates and times a person who looks like me has been seen by a Waymo while my particular Android phone is nearby, or dates and times they have seen [my OCRed car number plate].
> Video Clips captured by the LPR system will automatically be deleted after 30 days; although Images are deleted when no longer needed, the data obtained from the Images may be retained indefinitely. Should any information from the LPR Dashboard be needed to assist with a security or law enforcement matter, it may be retained indefinitely, in paper and electronic form, as part of the security file until it is determined it is no longer needed; in addition, it may be shared with local law enforcement who may retain it in accordance with their own retention policy.

Human drivers have dash cams, too. Maybe without as sophisticated a data ingestion system as google, but they could theoretically put their dashcam footage on youtube if they wanted to.
A ring camera can do image recognition and store durations of video where a person is in frame. I'm not sure what the privacy difference is between these two. Is lidar and radar recording that much more of a privacy concern than video recording.
I'm pretty sure between traffic cameras and security cameras lots of commuters on th street are being filmed. With or without Waymos

What bothers me regarding surveillance and self driving cars is that an executive sympathetic to the surveillance state could build a system that allows arbitrary surveillance of vehicles or housing by license plate or location. Eric Schmidt was a regular visitor of The Pentagon and Billionaires simply live in a different world than we do. So while some driver could happen to capture me and upload it to YouTube, Waymo could, if someone wanted, have a secret operations center which allows surveillance of all sorts of people, locations, and vehicles. The same way that AT&T had a secret NSA closet that split off major fiber pipes, some data pipeline could have an invisible filter that duplicates data matching certain variables and delivers it to a surveillance partner.

That would be incredibly expensive.
Those cars are taking in TB of information each daily. Scale that to 10s of millions of cars.
It's just not going to happen.
Maybe an ultra compressed representation of you that shares maybe 1 bit in 1 weight somewhere in a NN will live forever.
Fear not, your images and recordings will get piled on somebody's dashcam to do as their heart desires.
I got a dashcam in my Camry recording front and back everytime i drive. I have no interest in preserving those images outside of an accident, but who knows what sommebody else will.
We have no expectations of privacy in public spaces and ultimately I would trust Googles IT security more than some dude with a dashcam

Definitely a big privacy concern, especially for people like you who aren't using the technology, and haven't consented to giving your data.
But car crashes are the third highest cause of death in the US (https://www.cdc.gov/nchs/fastats/leading-causes-of-death.htm). As a society, I think the benefit outweighs the cost in this case, and we can (theoretically) continue to make progress on privacy as a society. Seems like much more of a step forward than a step back to me
No, that says “Accidents (unintentional injuries)” as a category are collectively the third leading cause of death, and that category contains a lot of things.
- “Person injured in unspecified motor-vehicle accident, traffic” is the 50th leading cause of death at 0.4% of deaths.
- “Person injured in collision between other specified motor vehicles (traffic)” is the 108th leading cause of death at 0.2% of deaths.

Dooring is so incredibly preventable with simple computer vision and some kind of actuator that adds an audible alarm and mechanical 3x resistance to the door opening when a cyclist is detected. The door should still be openable in emergency but should be hard to open until the cyclist passes.
(For cars that have both a normally-used electronic door open button and a manual emergency release (e.g. Teslas), the electronic button can use the car's existing cameras to detect cyclists first before actuating the door to open. This would be a trivial software change in the specific case of Teslas. The only thing I dislike about the Tesla setup though is that most non-owners are unaware of where the mechanical emergency release is; it is not obvious and not labelled.)
porphyra · 12h ago
> This would be a trivial software change in the specific case of Teslas
Tesla already has dooring prevention. If it detects a bicycle or something coming, it prevents you from opening the door the first time, and shows a warning. You can override it by trying to open it the second time, if you are sure.
Waymo already warns you if it detects road users when you open a door. They just don't actively prevent you from opening the door, but they could implement it in their next generation vehicles.
kajecounterhack · 12h ago
They won't have to if they use sliding power doors (the geely cars have them). They should have had them for the jaguar generation :)
Dooring people aside, what do you do if someone just leaves the door open when they leave their ride?!
tintor · 11h ago
You charge such riders additional penalty fee on their account.
Waymo needs to have staff in SF anyway to pick up cars that malfunction (flat tire, or just close the door).
overfeed · 10h ago
> Dooring people aside, what do you do if someone just leaves the door open when they leave their ride?!
Continue billing them for the ride and send an app notification or phone-call to their phone.
Other potential solutions: If the door is still not closed after n minutes, plead with passers-by, or offer a passing or nearby rider the chance to earn credit by closing the door.
ra7 · 12h ago
Oh, that's already a problem for them. There are videos of many Waymos stranded because the previous rider didn't close the door fully.

Health insurance companies should pay for it. Their costs would come down if they subsidize the full R&D cost of this system for all car manufacturers. It would work in their favor.
They're probably too stupid to think like that, though.
chris_va · 13h ago
Health insurance generally has a fixed profit margin (state legislation). They have little incentive to reduce cost because then the entire pie shrinks. A nice example of where well meaning legislation can completely backfire.
Of course, passing costs to all insurance companies is really the same as passing it to all people paying insurance premiums, at which point you can just use tax money to get the same effect. At which point, it's probably easier to regulate it and have the cost passed to everyone buying a car.
enragedcacti · 12h ago
You could probably design the latch jaws to have an electronically controlled second catch. It would activate whenever a cyclist is present so if someone tries to slam the door open it would catch with the door slightly open and trigger a warning. A second pull then opens the door no matter what for safety.
FridayoLeary · 13h ago
That would lead to ridiculously overengineered car doors. It's already incredible how such a simple thing like a door can be so unreliable on newer cars, with handles that sink into the doorframe when not in use, or a locking system that only works with battery power. I'm not sure that adding more complexity would be a net benefit for society.
toast0 · 12h ago
It's already there, my new fancy car has it. Push the lever to open with electronic help, pull the lever twice for mechanical release. The electronic help version checks for safety first (as long as you do it with a timeout from when the car was running/ready) We'll have to see how the fancy car does over time, but I did get one with handles on the outside that don't disappear.

I’m a fellow cyclist in SF and can only wholeheartedly second this. To add some extra anxiety, I’m usually riding a cargo bike, ferrying a child to or from daycare.
I still remember the first time I went through a four-way stop intersection and saw a driverless car idling, waiting for its turn. It was weird and nerve-wracking. Now… I’d much prefer that to almost any other interaction at the same spot.
philomath_mn · 13h ago
Best part is that they probably have data to show that all that patience costs the typical passenger mere seconds to a minute on 99% of rides.
This has always bothered me about aggressive or impatient human drivers: they are probably shaving like 30 seconds off of their daily commute while greatly increasing the odds of an incident.

I experienced this phenomena on my electric scooter. I could always scoot faster than someone walking but ultimately it makes little difference because I just spent more time for the crossing signal to turn green. So they end up catching up to me.
Now, when there's long stretch or when you have to go up hill, that's where the electric scooter begins to shine and makes the largest difference.

You are missing all the times where you are enough faster that you catch a green while the other person gets there on red and so they never catch up. It is easy to see/remember the times they catch up.

Or just implement vastly more automated ticketing systems. They are standard in many countries. They could be implemented with limited-purview privacy preserving architectures where that aligns with expectations and values.
But people speeding, driving aggressively, driving anti-socially (by trying to speed past lines and cut in at the front), running lights and stops... this could be squashed forever, saving lives and ultimately making life more pleasant for everyone.

My favorite thing from my first Waymo ride was watching a lady walk up to the middle of the street to cross. The Waymo saw her, slowed, and waited to let her cross. She smiled and waved and immediately felt dumb because who is she waving to? Do I wave back? We laughed at each other as it drove away.
Ever since then my fear melted away. They see every direction, never blink, and are courteous and careful with pedestrians.

I wonder how will this behaviour evolve over time? Right now waymo is definitely prioritising safety, but as the tech matures (and competition grows) will the systems start to prioritise speed and so little-by-little start cutting the margins they give to pedestrians? As with any digital platform this degradation wouldn't be explicitly chosen, but just the consequence of many little A/B tests designed to optimise some other metric
biophysboy · 13h ago
I am also hopeful that Waymo has other positive externalities for bikes/pedestrians: less need for parking spots, car ownership, etc. At the same time, I guess you could say the same for rideshare, so it would depend on if robo-rideshare is cheaper than ownership
VOIPThrowaway · 13h ago
My prediction is that car usage will go thought the roof when AI cars work.
People can have a stress-free commute to a nice house in the countryside and work in the cities. Because the car is electric, it will be inexpensive to run.
crazygringo · 12h ago
Commute time still matters, and congestion pricing will become the norm.
I can read on the subway, but while a 20 min subway ride is fine, an hour each way is still a lot, and a two hour train commute just doesn't leave much time in your life for doing social things.
Also, I think there's going to be a huge surge in in-demand AI buses. Rideshares will take people to a random spot, you'll wait 2 minutes for a predetermined seat on a specific bus, and then switch to a rideshare van for the last 5 minute drive to your office in the city.
It's just going to be so much cheaper. With economies of scale and urban congestion pricing, you'll have to choose between dropping $45 on a dedicated hour-long door-to-door car trip, or $6 for the car-bus-van version which is only 20% slower anyways.

Late-stage capitalism is a defunct theory based on Marxism.
Real, actual capitalism results in competition which drives prices down, as long as there are two or more competitors and antitrust law is enforced. Which is generally the case.
And in the case of monopolies like city buses, cities set prices directly in response to democratic pressure. By your argument, NYC subways ought to be $25 a ride... but they aren't.

LorenPechtel · 11h ago
Yup, and if every car is computer controlled and in communication with nearby cars you can safely reduce spacing. Most of that space between cars is due to human reaction time. (And even then that's not always enough. 40 years ago, I'm going along, geezer is being awfully slow about their left turn so I lightly apply the brakes. Geezer then proceeds to completely stop, utterly unaware that I'm heading right towards his door. I slam on my brakes. I was able to stop for said geezer but the woman behind me didn't have the usual warning of brake lights flaring and came up a couple of inches short in stopping. Geezer proceeds off, apparently completely unaware of the accident he caused.
(And that was not the only close call I had with that geezer at that corner.)

bluGill · 13h ago
It will only be cheaper if you don't drive much anyway, and you are the type who would never be seen in a car more than 3 years old.
If you drive a lot (like the person in the countryside) the car that is there when you want to is worth owning vs a shared car that you might have to wait for. Plus by owning the car you can just leave your golf clubs in the trunk.
If you can stand being in a used car you will discover that shared cars are all more expensive just because at the first sign of cosmetic wear they get rid of it while seats that have been sat in a few times are still good enough for many more years. (unless you almost never drive anyway)
Because of the above I don't see much growth in the shared car market. There will be some because there are people who don't have parking, people who don't drive much, and people who demand a new car that they don't otherwise care about. However the vast majority of people will still own their own car.

I agree, to a point. Waymo has some vaguely aggressive habits that are usually for the best, like initiating their turn forcefully, but there is one specific thing I've noticed. Coming down Mason and turning left onto Bush it is a one way street turning left onto a one way street. Twice now while trying to cross with the light Waymos have crept into the crosswalk while I was already crossing. It's very unsettling.
I imagine the weirdness of the situation (legal left on red) triggers it's "creep forward so I can see" logic but it definitely shouldn't be blocking a busy crosswalk there when there is little to know chance it will be able to turn AND peds from both sides.

This will surely get some skepticism as it's a Waymo study, but it's nice to see a real‐world dataset this large at 56M miles. An 85 % drop in serious‐injury crashes and 96 % fewer intersection collisions is a strong signal that Level 4 ADS can meaningfully improve safety in ride-hail settings. Still curious about how much of that comes from operational design versus the core autonomy, but it’s a big leap beyond “novelty demo.”
Really excited for autonomy to become more and more common place. People drive more and more like distracted lunatics these days it seems

manquer · 12h ago
Here is one,
Humans drive in all weather conditions on all types of roads and also many types of personal vehicles of varying ages and conditions.
Waymo is limited to few specific locations with decent roads and does not drive in poor weather and is limited to a relatively large and safer expensive SUV that is maintained professionally in a fleet.
Studies like this rarely account for such factors , they are compare optimal conditions for self driving to average conditions for humans.
Even if waymo was better when accounting for these factors , if it was much worse in the conditions humans typically are expected to drive [1] they self driving is still less safe than humans on average .
A better comparison could be with professional taxi drivers for the same city (not Uber or Lyft).
I wouldn’t be surprised if Waymo is either on par or poorer than this group .
[1] no study will ever show this as they wouldn’t be able to trial it under those conditions if it is not safe enough
jedberg · 11h ago
> A better comparison could be with professional taxi drivers for the same city (not Uber or Lyft).

If you've been in both a human drive cab and a Waymo, you'd definitely not say this. I see cabs have accidents all the time. Never seen a Waymo have one.
Also, being in a Waymo feels much safer than a human driven car, even my own when I'm driving!
I highly doubt taxicabs are safer than Waymos.
In fact, here is some data:
Over every 1 million miles driven, there are 4.6 cab crashes, 3.7 livery car crashes, and 6.7 crashes with private cars. And according to Waymo, they have 2.1 crashes per million miles.
manquer · 7h ago
> 4.6 cab crashes, 3.7 livery car crashes, and 6.7 crashes with private cars.
> Waymo 2.1 crashes
The numbers become much less 80+% plus claim in the article as you remove factors. It comes closer to 30% with professional drivers.
Livery car is still not always well maintained a high sitting SUV with better visibility[1], perhaps with all these factors included if it is 20% better it is impressive technical achievement for sure, but not going to create headlines anywhere.
The point is the methodology is not as objective as it could be, and this is biased/selective claim, not that self driving cannot be better than humans.
[1] Also there is major difference in the price point between Waymo and Livery cars, I cannot say how it will influence rates but the different rates means different class of clients using at different times of day/night to different locations that needs to be normalized for.
jedberg · 6h ago
The percent improvement doesn't really matter though. The fact that it is better than even just professionals still means that there are fewer crashes, and therefore they are improving overall road safety.
manquer · 3h ago
* In a better car, serviced much better than the average professional vehicle.
The % matters because it is close enough excluding these factors, so we can not definitely say it currently better than humans yet, close but not conclusively so.
That is not a argument against them. It is a simple function of economics, i.e. as long as it better than Lyft/Uber(they are already) that is the price point that Waymo operates at, so it is safer for most users and easy choice to make.
However if you can afford and regularly use high quality private livery car services then the data has to be lot clearer to make the switch.
riquito · 11h ago
> Waymo is limited to few specific locations with decent roads and does not drive in poor weather
the study is comparing Waymo to accidents occurred in the same cities where Waymo operates, and my understanding is that Waymo drives 7 days a week, 24h a day in those cities, so same roads, same weather. Seems a legit comparison
notTooFarGone · 2h ago
Also there is some sort of bias not accounted for: People drive when most people drive and most people are stuck in the most dangerous area: traffic. Waymo driving at night on empty streets is not a good indicator for accident prevention when measured against the average human, who is stuck mostly in traffic.

I am very curious where waymo is at in adverse conditions. Do the cars totally lock up and become useless? Or are they at the level of your 65 year old mother driving in a thunderstorm at night? Passable, but nothing they are gonna put their name on.
Seems they intend to come to Washington D.C. next year, which does get a pretty wide gamut of weather.

Waymos drive in all weather in the cities they're deployed in; cities where people crash all the time in all types of weather.
manquer · 7h ago
Waymo ( and self driving programs as well) have been careful not to go for public large scale deployments in any city with difficult weather and for good reason focused on cities like Austin, Phoenix, Los Angeles, SF[1] so far with easy driving weather.
There have been promising progress and there have been hints of a New York trial soon, but it it well known that self driving cars have not done large scale trial in cities with bad weather.
[1] Yes, I am aware SF gets a bit of bad weather with fog and rain but not nearly not as much to make driving quite unsafe like somewhere that gets a feet of snow in 24 hours in winter, and likely promixity to engineering HQs and favourable regulatory climate influenced the SF choice.

It's an incentive problem.
Uber/Lyft drivers are strongly incentivized to drive as quickly and aggressively as possible.
The individual drivers are trading risk for cash.
A company like Google isn't going to make that trade because it's actually the wrong trade across millions of hours.
rozap · 14h ago
There was a study a few years back that showed male uber drivers earned more than female drivers. How could this be so, when the dispatch algorithm doesn't discriminate? Turns out men just drive a little faster in the aggregate so they made iirc around 3% more money.

I think the problem is a general one about drivers, not just ride-sharers. I live in a fairly busy area and I am beset by aggressive drivers any time I need to cross a busy road. So many drivers simply ignore pedestrians by default. Not that many of them have Uber or Lyft signs in the window, if anything commercial drivers tend to be a bit more careful in my experience because the downside risk is being unable to work any driving job.
bluGill · 13h ago
About half of commercial drivers is my conclusion. (though I'm not collecting statistically valid data) Just judging by the number of commercial vehicles who drive into the crosswalk I use often.

Good point: Part of Waymo's safety stats comes from settings that are probably tuned right now in favor of safety stats even if it means a longer or less-profitable ride. It doesn't care if you're going to lose your job if you're five minutes late.
So a fairer comparison would be contrasting Waymo rides to trips conducted by the Ultra Safe Even If It's Slower Chauffeur Company.

> they've got their settings tuned in favour of safety stats is the whole point
For now, yes. My point is that there's very often big gap between "how safely does it work in a lab when the people running it are trying to play up its safety" versus "how safely will X actually work once we start using it everywhere."
Manually-driven vehicles could be a lot safer if they were being prototyped under strict guidance as well!
If we want self-driving cars to retain the same safety later, there needs to be something which prevents humans from flicking the safety-versus-speed dial a little bit over and over in order to make quarterly earnings projections.

I don't understand what you're trying to convey with this tautology.
_________
Imagine two fleets of cars/planes/whatever with utterly identical equipment and expertise. The only difference is that for one of them, the management is being pressured by politicians to demonstrate a high degree of safety.
For that scenario, wouldn't you agree that the better-safety comes from temporary external cause? And also agree that the better-safety is unlikely to persist long after the incentive disappears?
[TLDR] Some portion of Waymo's safety-stats are due to the investor/regulatory context in which it currently operates, rather than the underlying technology; the effects of that portion will not be permanent; this should affect how we do comparisons.

ChadNauseam · 3h ago
I disagree that "the effects of that portion will not be permanent". The safety level can be set to whatever is desired by governments, since governments control how much liability Waymo has. We haven't seen cars get less safe, we've seen governments force car manufacturers to make them more safe. (As well as institute seatbelt requirements, speeding cameras, etc.) I expect the same to happen with self-driving tech. The benefits to driving more aggressively are also likely to be pretty small to the company - I don't think I've ever been in a Waymo ride that's spent more than a minute waiting for pedestrians. So even if they were twice as aggressive, that's saving 30 seconds per ride. Probably not going to have a huge impact on the bottom line.
Also, if you want to include the speculation that they'll make their cars drive more aggressively, you should also include the speculation that the technology will become better and the driving tech will become even safer than they are now.

I’ve also been stuck in a Waymo that couldn’t figure out its way around parked buses, so they have edge cases to improve. But man does it feel like I’m living in the future…
jessriedel · 13h ago
> I used an Uber on the way here and the car was dirtier
To be fair, the fact that Waymos are fancy clean Jaguars is kind of ancillary to the main technology. The tech is currently expensive, so they are targeting the luxury market, which you can also get on Uber if you select a black car or whatever. The people willing to pay for that are less likely to make messes, and the drivers put more effort into frequent cleanings.
Once the tech becomes cheap, expect the car quality and cleanliness to go down. Robocars do have some intrinsic advantages in that it's easier to set up a standard daily cleaning process, but they will still accumulate more garbage and stains when they are used by a broader cross section of the population and only cleaned during charging to reduce costs. (Of course, cheaper and more widely accessible tech is good for everyone; if you want a immaculate leather seats cleaned three times a day, you'll generally be able to pay for it.)
kajecounterhack · 12h ago
I don't think the Jaguars are particularly spacious or nice. They just got a good deal on the platform. If anything, given the commodity nature of vehicles I'd expect car quality to improve.
Cleanliness doesn't seem that related to how expensive the tech is either - if anything it would only go down if it ceased to affect willingness to pay. As it stands, clean cars are important to their customers. If usage increases, cleaning can ostensibly increase too, no?
Rebelgecko · 12h ago
YMMV but for me Waymo is usually significantly cheaper than Uber Black and more comparable to UberX (within a few bucks before taking tip into consideration)
AStonesThrow · 12h ago
What is 1000% better about Waymo than rideshares is the liveried fleet vehicles.
Regular taxis around here are also liveried fleet vehicles. Especially the very large providers: if I summon a taxi cab, I know for sure its make and model, and its paint job will clearly indicate it's on-duty as a taxi cab. You don't understand how incredibly important this is sometimes.
For the simple yet panic-inducing task of strapping on my seat belt: I can do it in seconds with a liveried vehicle, because I know exactly what to expect. In a rideshare like an Uber, every time a car arrives, it is a new make, new model (I swear to god what the fuck is a "Polestar"???) and the owner might have wrapped on some crazy aftermarket seat covers, and finding the seat belt and its mating latch is a huge drama. I've taken to leaving the passenger seat open, until I can get the belt safely latched, because otherwise the driver will promptly take off, and panic will increase 3x as the vehicle is moving and I can't find the seat belt.
Other than that, the liveried vehicles are easier to maintain; they're easier to keep clean; they're much better for brand recognition. Hallelujah for Waymo!

Anecdotally, as someone who bikes a lot in SF, Waymo's are a lot safer than human drivers simply because they follow the letter of traffic laws. Stopping at stop signs, waiting for pedestrians to clear the box, following the posted speed limits, etc.
MattGrommes · 10h ago
Just following the letter of the law is so huge. Even people who think they're being nice by doing something out of the ordinary make the situation so much more dangerous because now you don't know what's going to happen.

I was just on a business trip to San Francisco for a few days, and I observed the near opposite of this from the Waymo fleet in SoMa:
* Waymo vehicle creeping into the pedestrian crosswalk (while the pedestrians had right of way to cross), which caused someone to have to walk around the car into the intersection ahead of the Waymo.
* Waymo vehicle entering a dedicated bike lane and practically tailgating the bicyclist that was ahead of it.
These might be safer than human drivers in aggregate and normalized by kilometer driven, but they drive like humans — greedily and non-defensively. I wouldn't want one these anywhere near a high-pedestrian traffic area ever, and I feel the same about human-driven cars, too.
johnmcd3 · 13h ago
> * Waymo vehicle entering a dedicated bike lane.
In California, California Vehicle Code § 21209(a)(3) expressly permits a motor vehicle to enter a bicycle lane “to prepare for a turn within a distance of 200 feet from the intersection” -- among other cases. (The vehicle must yield to cyclists in the lane.)
yonran · 1h ago
The vehicle code not only permits cars to enter the bike lane prior to a turn, it requires them to do so (https://leginfo.legislature.ca.gov/faces/codes_displaySectio....). My brother failed his first driving test because he didn’t know that he had to enter a bike lane on the left side of Fell St right outside the DMV (back before they separated the bike lane).
sidibe · 9h ago
I hope that means yield to cyclists ahead of them. To me the whole point of getting in the bike lane is to avoid cases where the cyclist going straight is in a blind spot during the car's right turn. As a cyclist I'll sometimes get into the car lane at intersections to make sure I'm seen. seems like the car being required to let the bike behind them go straight is exactly what you'd want to avoid
standardUser · 13h ago
> I wouldn't want one these anywhere near a high-pedestrian traffic area ever, and I feel the same about human-driven cars, too.
Much of San Francisco is a "a high-pedestrian traffic area" and Waymos operate in those areas constantly and more or less flawlessly. As someone who lived carless in SF for nearly 15 years, I see nothing but upside from more Waymos and less human drivers on those busy streets.
TulliusCicero · 12h ago
Note that you have to enter a painted bike lane before turning, because it's safer to do it that way rather than crossing the bike lane right at the turn.
I know it can seem discourteous to cyclists, but it really is the smarter way.
JumpCrisscross · 13h ago
Neither of the examples you cite strike me as particularly dangerous nor even illegal. The pedestrians were given the right of way. And entering bike lanes is fine for crossing or short distances where merited unless grade separated.
matttproud · 13h ago
A vehicle that becomes blocked in a crosswalk is unsafe for pedestrians who want to use that crosswalk if it forces the pedestrians to walk around the blocking vehicle. There are crosswalks in SoMa that provide for 45 seconds or more of crossing time. A Waymo that enters one of these crosswalks after 15 seconds into the 45 seconds allocation blocks the crosswalk for the remainder of the 30 seconds. This presents an unsafe situation for all existing and future pedestrians (e.g., a pedestrian who inadvertently steps into the intersection while trying to go around the blocking vehicle).
We also know that in North America that the municipal services skimp on grade separation for bike lanes for budget and political reasons. I did bike in San Francisco when I lived there, and these non-shared colored lanes never ever felt safe.
I can guarantee that if you leave your North American context for a couple of years and come back to it you'll find CA Vehicle Code § 21453 unsatisfactory.
JumpCrisscross · 13h ago
I totally agree that grade-separated bike and pedestrian lanes would be better. What I’m arguing against is that this behaviour by Waymo is less safe than San Francisco’s human drivers given the rules as they are.
matttproud · 13h ago
Don't think for a minute I want human drivers anywhere near bicyclists or pedestrians or assume they are anywhere better for general-purpose driving. Human drivers are awful, but I'd posit the behavior of these automated vehicles isn't much better toward making a welcoming road environment as they are programmed. The laws — particularly for California and what is treated as standard in North America — don't help matters at all.
kfarr · 14h ago
This is great and there’s another area of influence that I’ve heard other traffic engineers discuss: platoon pacing. A platoon is the word that traffic engineers give to a group of cars traveling together. A platoon is most explicitly visible on a corridor with signals timed for a green wave, but occurs in many other contexts.
Human drivers often race when in a platoon— not even on purpose it’s just an instinct to go as fast or faster than other cars which has a feedback effect to increase platoon speed.
Waymos, following the exact speed limit, don’t do this. On 1 lane streets they literally set the platoon pace to the legal speed limit.
The effect of this is hard to study and quantify but it’s a real and positive impact of self driving cars on city streets. Haven’t seen research on this topic yet.
wffurr · 14h ago
This also came up recently in a thread about speed governors: https://news.ycombinator.com/item?id=43812856 Just a few governor-equipped vehicles (e.g. from public fleets or prior speeding offenders) can reduce speeding on the whole road.
sneak · 12h ago
On most roads, speeding isn’t a safety issue and shouldn’t be discouraged, as road throughput is important. Speed limits are usually set too low due to standardized inflexible policies or desire for revenue.
On some roads, however, it is a massive safety issue, and everyone is driving unsafely because the road is designed badly for its intended purpose. (So-called “stroads” are the canonical example.)
Mawr · 2h ago
Yeah and we should definitely leave deciding the appropriate speed to the drivers. Because, uh, throughput is important, got it. Is safety important? Who knows, but throughput definitely is!

squigz · 27m ago
I would expect "most roads" to be comprised of residential roads, and I find it hard to believe speeding on those roads is not a safety issue.

There are currently over a million fatalities from road traffic crashes every year, being the leading cause of death for the 5-29 year age group[0].

The goal of punishment for driving offenses is, in my eyes, largely about reducing unsafe behavior - not just to make someone suffer. Fines/incentives for manufacturers and fine-tuning of models based on incident data should fulfill this purpose.

One can fine the companies and executives.

How do AI cars fare with those instinctual "decide which way to swerve in a split-second" scenarios that come up maybe once every 10-20 years over the course of a driver's history?? It's happened to me about 2-3 times and I've always made the "(assumedly) correct" split second swerve decision. Wondering if that is a "human/instinctual" skill and if AI cars do just as well or better, or perhaps not as good? I don't have any evidence backing this but my gut tells me these scenarios are something that a human driver would handle better than AI.
Hard to say for certain, but it looks like just braking probably wouldn't have avoided the collision.
JumpCrisscross · 12h ago
I’d argue that’s more straightforward collision avoidance than a swerve since the rider was to the side when Waymo turned. As such, there wasn’t a choice between braking and swerving. One had to do both, and there was no real optionality as to whether to swerve right or left.

Aloisius · 12h ago
The correct answer is to not drive so fast (or at all) in conditions where braking might lead to a skid. I'd expect an autonomous vehicle to be rather better at this given they can hook directly into the electronic stability control system in a vehicle and constantly monitor temperature (and ideally measure upcoming road temperature).
Also, shifting into neutral is really only a thing for old vehicles without ABS/ESC. In modern vehicles, you let your foot off the gas slowly.

This is only true with 2WD and no automatic stability control, and if you’re going down a slope. For every other case, ABs will out perform in snow and gentle braking will evenly distribute traction force with stability control doing microsecond evaluations.
bluGill · 12h ago
You still need to be in neutral as the ABS/stability control doesn't control the engine. 2wd makes no real difference other than rear wheel drive tends to be the most susceptible to this issue, but any wheel can lose traction.

I spend about 5 months every year driving in snow and ice - this is the first I'm hearing about dropping it into neutral. Can you elaborate on when that would be appropriate? Obviously you shouldn't be slamming on the brakes, but they do work fine in snow and ice. I don't see how rolling into things while not in gear is an improvement?
hn_acc1 · 10h ago
I think the OP means in a manual transmission. Auto will decouple at low speeds / engine braking won't be as severe. In a manual car, in 1st gear, I could possibly see it.
As someone who grew up BEFORE ABS, drove in the winter (in Canada), including first winter owning my own car with sport tires because I couldn't afford winter tires, spun / slid a few times even with top-of-the-line winter tires, etc.
ABS is a game changer in the snow. I used to go to an empty parking lot every winter during early snowfalls to play around and skid, start/stop, etc. Even EARLY ABS ('94 VW) means that 98% of the time (IMHO), the answer even in snow/ice is "slam on the brakes". Sure, you might have a few percent longer stopping distance than an expert who can do threshold braking - are you an expert? And the fact that you don't lose control of the steering is a huge advantage.
creaturemachine · 13h ago
I remember being taught the neutral trick for emergency braking back in the 90's, and it had nothing to do with traction in poor conditions. It was simply to remove any engine power that might extend your braking distance. It's definitely bad advice in any modern car.
JumpCrisscross · 13h ago
They mean go into neutral and lightly brake. In a 2WD car, the braking force applies more strongly to the non-powered wheels. Since those were traditionally the back wheels, this meant when going down a hill the front wheels would have more traction. Those are also your steering wheels, which means them locking up is bad. Again, this is the sort of advice that is germane in highly restricted environments which become folk knowledge and later mis applied by humans in ways that reduce safety.
(You also only get into this scenario when your stopping distance is shorter than your reaction time and perception length. Something automated drivers can manage better than humans.)
ecshafer · 8h ago
If you are in a situation where your car is sliding, like down a slick hill. You dont hit breaks, you put the car into neutral and steer into the way your car is sliding to try and keep the car on the road.
indigodaddy · 13h ago
I think it's often about when you're on rural single lane roads and perfectly bad ice/snow/slush conditions where you need to keep your speed very low, and sometimes even very moderate braking can cause your vehicle to veer off the road and into a snow bank, not necessarily the need to avoid something in front of you
bluGill · 13h ago
When you let off the throttle your wheels start driving the engine and slowing you down. In snow/ice that engine breaking alone can be more braking force than is safe and so you go into a skid. Shifting to neutral removes engine braking and allows for more controlled slowing down.
bryanlarsen · 12h ago
If hit the brakes is the wrong answer, you are driving too fast.
SchemaLoad · 9h ago
Almost all of these tricky situations are avoided by slowing down and giving more space around hazards.
indigodaddy · 13h ago
I disagree. High percentage of these scenarios are at speeds and scenarios where hitting the brake would not prevent a collision and a quick swerve is the only option to not collide. Obviously your quick swerve could cause another collision so I guess it's which decision on average causes the least harm/death? I agree though that most people's extinct would be to brake. Mine never has been though.
bluGill · 12h ago
If you cannot brake you are following too close. I know everyone else does it (except 3/4ths of semis!), but you can be the one who maintains a long following distance and thus can stop in time. Every time setup the long following distance 5 cars jump into the gap - but then the gap remains as no more do.

I watch a lot of car accident videos and I've seen that happen exactly once.
Perhaps you mean the far more common scenario when the car in the next lane simply decides to merge into yours? Nothing about that is random[1] and the response in 90%+ of cases is just to let off the gas for a few seconds. That's it.
[1]: In most cases, it's because your lane is open and theirs is about to be backed up. You'd want to switch lanes too, so it really shouldn't be surprising they do.
The rest are mostly people realizing at the last second they want to turn right/left at an upcoming intersection (or highway exit). Again, predictable.

If it’s 1989 and you don’t have ABS, yes. Otherwise, swerving is a gamble [1]. If you don’t have time to stop, you physically don’t have time to evaluate and choose a right or left swerve. You’re trading the certainty of a head-on collision with whatever is in front of you against the uncertainty of what’s to the right or left, compounded with all the fun that comes with a side/tumbling collision and increased risk of not hitting a car.
Right, so you've created a dangerous scenario by speeding and by the direct consequences of your actions you're now forced to execute a dangerous manoeuvre of swerving. Maybe, just maybe, the solution is not speeding.
> I agree though that most people's extinct would be to brake. Mine never has been though.
...
You operate a motorized vehicle and your first instinct when seeing anything dangerous ahead is to do something other than braking?
Mawr · 2h ago
- Humans have awful reaction times, so the "AI" cars should fare 10-100x better. "split-second" is laughably slow to a computer.
- How seldom these scenarios come up for human drivers is a huge disadvantage for them. For self driving, it doesn't matter, the cars' reactions can be simulated in arbitrary scenarios as many times as needed, so even the rarest of scenarios can be ensured to be handled properly.
- There's nothing special about the decision to swerve vs to say, brake. I'd expect self driving cars to not need to swerve nearly as often because the need to swerve probably only ever exists due to excessive speed and/or poor following distance to the vehicle ahead.
> It's happened to me about 2-3 times and I've always made the "(assumedly) correct" split second swerve decision.
Easy question: Did you make that decision with full awareness that you would not end up in a collision path with another vehicle by swerving? Oops.
Even if you did, how many drivers do you think would "instinctively" swerve into another lane and get hit by an oncoming vehicle because they do not maintain constant situational awareness around their vehicle? The majority, at least.
OJFord · 13h ago
Probably better? 'Who' can process more data faster is likely impossible to answer, but (e.g.) Waymo can train on those scenarios and have way more 'experience' than any individual driver who's seen it once every 10-20 years of their driving career.
indigodaddy · 13h ago
Yeah it's interesting, these scenarios are generally at high speeds on an interstate highway, and generally involve some level of predicting what the villain driver is going to do (split second prediction though mind you, it all happens in the blink of an eye), and sometimes the right thing to do is to swerve (if no one is adjacent in surrounding lanes) whilst either not using the brake at all or almost no braking. Basically avoid the brake and do your quick swerve after you've confirmed there is no one in the left/right adjacent lane or close enough behind you. Once again this all happens in the blink of an eye. Perhaps AI would be better? I'm not complete sold though..
creer · 6h ago
One big difference in favor of the software is your "after you've confirmed there is no one in the left/right adjacent lane or close enough behind you." The car has been looking in every direction the whole ride. The car already knows what there is to know about all the neighbours. A huge advantage over the human driver.
I feel also that the car having a far better experience of its kinematics / dynamics / features is also a huge advantage - see the good old drifting parallel parking videos.
After that there is the concern about computing reaction time. Can it get stuck hesitating? Clearly the cars hesitate a lot in generally safe places. But we have seen some videos already of a Waymo very smoothly dodging someone running out from in between cars (they were already tracked), and someone mentioned a scooter incident. Hopefully we'll see more videos of emergency responses.
Another comment mentions "r/waymo or r/selfdrivingcars for lots of videos of Waymos avoiding objects."
warkdarrior · 13h ago
I'm ok if the AI car makes an incorrect decision once every 10 years.
jeffbee · 13h ago
It's just ape hubris that makes you think these were the right swerves instead of just dumb luck that you did not flip over the center barrier head-on into a school bus.
The Waymo doesn't have to swerve as much as a human because it can see a mile away and never blinks, and it knows that the right thing to do in every swerve-worthy situation is to slam on the brakes to take the energy out of the event. It also drives around with the brakes pre-pressurized because it isn't trying to compensate for the fact that its control system is partially made of meat. Anyway you can go to r/waymo or r/selfdrivingcars for lots of videos of Waymos avoiding objects.

So, what’s it gonna take for Waymo to start selling retrofit kits for existing cars?
If a $10,000 investment reduces the chances of a serious accident by 90%, the corresponding reduction in insurance rates might have a payoff within a few years. Especially if adoption starts to push rates up for customers who don’t automate. I can’t take a taxi everywhere, but I’d sure like it if my car drove me everywhere and did a better job than me at it too.

porphyra · 12h ago
It honestly feels like they spend years validating each new platform, e.g. the Zeekr was announced years ago and only recently are they very rarely seen on the streets but only as Waymo Engineering mules. Likewise the transition from the Chrysler Pacifica to the I-Pace took a while. Hopefully they figure something out to scale up to more platforms soon. They announced a partnership with Hyundai a few years ago, also with nothing to show for it.
Of course, safety first, so they should take their time and not rush things...

The zeekr vehicles were heavily affected by changing regulations and tariffs around Chinese made automobiles. The Hyundai vehicles haven't started production yet. They're in an awkward situation because they made a bad prediction about the political direction without a backup plan and it went south right as they were entering production.

pavon · 13h ago
In many states, including CA, individuals can post a bond instead of carrying insurance. Companies with fleets of vehicles can also self-insure. In both cases the car owner is liable to pay any damages that insurance would normally pay.

Large companies with fleets of vehicles often self-insure.

Interesting!
When I was much younger, I worked for a couple companies that had (what I would consider) large fleets of vehicles, and they all were insured through an insurance company. I guess I just assumed that's how it was. I wasn't aware self-insuring was a possibility. Thanks.
bluGill · 12h ago
Companies can self insure. That doesn't mean they have to. Your accountant can run the numbers to figure out if it is worth it.
Often self insure means they still pay an insurance company to handle the paperwork, but when there is a claim the company pays it.

Self-driving is probably still new enough that insurance companies wouldn't have good actuarial data to properly price the risks, so they'd just have to charge exorbitant rates.

The problem is that Waymos can't replace cars (or even Ubers!) since they depend on human oversight and problem-solving. Even at a 20:1 ratio it is not feasible for autonomous vehicles to employ 10m people to account for every American on the road.
xnx · 14h ago
This is a very confusing position. Every Uber has full-time 1:1 "oversight". Waymo has a support team that only directs actions (not remote driving) when the vehicle requests. I would be very surprised if the number of Waymo rides that need any intervention at all is greater than 1 in 20.
AIPedant · 13h ago
My point is you're not going to get much more than half[1] of those Uber drivers into a Waymo control center, even if they're facing unemployment. The workers have to come from somewhere. And it has to be somewhat regular hours, surge oversight doesn't make sense.
[1] Edit - I meant 5% not half, I was on the train and very frustrated with these comments. (not yours, though it seems bad faith to say "not remote driving" when I said "problem solving." The problem has always been the 1-5% of driving which truly requires sophisticated intelligence, that's why the oversight is there.)
Every Lyft driver I've spoken to drives because a) they like driving b) they like choosing their own hours and c) they don't want a boss. Telling them to go into an office for an 8 hour shift with a manager is not gonna work, they will find something more appealing. It's a different kind of employee. (I would enjoy that line of work but I would hate to drive for Uber, way too stressful.)
xnx · 9h ago
I don't think Waymo needs a significant amount of vehicle support staff now, and will need even less (per vehicle) in the future. The ratio will probably be something like the number of elevator repair people to number of unattended elevators operating smoothly.
I emphasized that Waymo staff does not drive vehicles remotely, because this persists as a common misconception.
Scaevolus · 14h ago
The human oversight is mostly to tell off people breaking rules in the cars, not to fix the driving, and is quite easy to automate as they scale.
AIPedant · 12h ago
That might be what human overseers are mostly doing minute-to-minute but it's not why it's necessary. The problem is AI simply does not have the real-world problem solving ability to handle all the minor inconveniences and surprises on the road.
IrishTechie · 14h ago
Americans only spend 3% of their time driving, so it's maybe closer to 300k than 10m. Still not scalable at that though so the key will be driving that 20:1 up, which seems very possible given enough time.
Where does the 20:1 stat come from? Does anyone know how may human interventions Waymo has per trip or per mile? How much human time is needed per intervention? And are the intervention rate and human time increasing or decreasing over time?
worldsayshi · 14h ago

Waymo doesn't say very much, but other self-driving services have been more open. It is things like "the fire truck is at a weird angle and the car didn't know what to do, draw a path where it pulls slightly into an oncoming lane so it can get around." A lot of common sense stuff which is far beyond the reach of AI in 2025.

boshalfoshal · 9h ago
This may be true, but paradoxically, the data might be slightly skewed since Tesla's driver monitoring system (which is only active during autopilot) actively rewards drivers who are paying attention.
So is the accident rate lower because people are forced to be more attentive during FSD? Or is it genuinely lower (i.e, if you took out the driver, would there be less accidents)? To be fair, I'd still wager that yes, FSD is probably statistically way better than the average driver.
Maybe some combination of miles per intervention + accident data would give more insights into that.

It's a great start, but also shows how driving is not a navigation challenge as much as it is a socialization challenge. If I drove right up to some responders dealing with an emergency and repeatedly refused to stop then I could be in big legal trouble and could end up with fines and possibly an arrest. This has not happened with Waymo vehicles because there is legal ambiguity about who is responsible in such cases. Realistic analysis shows these vehicles have a driving record similar to that of overconfident teens which is worrisome.

While driving a car, it is possible to do something, even on accident, that can land a person in jail. These crimes do not have the option of paying a fine in lieu of prison time.
A "self-driving" car can cause the same accident but gain advantages over a human driver that the person ultimately responsible is no longer held to the same set of laws.
This seems to undermine foundations of law, placing the owners of those assets into a different legal category from the rest of us.

The reason they investigate every airplane crash for a root cause is not necessarily because the number of deaths tilts the statistics, it's because they are highly complicated mechanical and electrical machines where there is always the chance for a systematic fault that will doom many further planes if not found and rectified.
The same of course applies to self-driving cars; they are literally cars driven by software, of course you need to do a root cause investigation every time to rule out that it's not a bug in the software that will kill another person (and many after) when the next car happens to go down that rare branch of the system.
It's embarrassing to see that the people that call themselves engineers at these companies have not held their work to this standard, and are instead publishing glossy brochures making whacky statistical arguments.

I've personally read through the root cause reports for most of the notable AV accidents. They're not always quite as intensive as aerospace, but I'd be hard pressed to describe any of them as wacky statistical arguments.

> The US drives about 3.2 trillion miles per year. Waymo has 56.7 million miles over several years. Their percentage data is essentially useless.
No, that's not how statistics works.
The percentage data's accuracy depends mainly on the number of incidents recorded (and somewhat on the rate of incidents). But the percentage of the whole is completely irrelevant.
If you are basing something on 10 incidents but it's 50% of the total, it's still terrible accuracy.
Whereas if you are basing something on 100,000 incidents but it's only 0.1% of the total, it's still going to be quite accurate, assuming the incidents come from the same overall distribution.

Yeah, that’s fair, but is implicit since I’m arguing against the “sample size is inadequate” POV, not the “there are distributional biases in data” POV. There are a gazillion ways to adjust for these biases (ex. propensity score matching) going beyond just user-base but also including weather type, road type, location, time of day, day of week, traffic density, pedestrian density … that can be done easily with far less than the sample size waymo has. And I bet they do these adjustments.
timewizard · 13h ago
> If you are basing something on 10 incidents but it's 50% of the total, it's still terrible accuracy.
The ratio of 3.2 trillion to 56.7 million, which is already incredibly generous to Waymo's position, is 5 orders of magnitude in difference. So any calculations from Waymos data are going to be insanely inaccurate and not something you can extrapolate from.
The main, and most obvious case, evidenced by this, is Waymo does not operate where snow falls. Human beings do.
We're missing so much of the picture I don't think you can say Waymo's are 75% less accident prone, or 80% less likely to hit a pedestrian. Those are just nonsense numbers.
achatham · 13h ago
The paper under discussion only considers human accidents in similar environments to where Waymo operates. So it's only making a claim about like-for-like driving.

Our safety research team is interested in this topic, too! In a previous study, they've tried to model it:
> Building on that, the Collision Avoidance Benchmarking paper presents a novel methodology to evaluate how well autonomous driving systems avoid crashes. The study, which to our knowledge is the first of its kind, introduces a reference model that represents an ideal human state for driving—the response time and evasive action of a human driver that is non-impaired, with eyes always on the conflict (NIEON). Put simply, unlike an average human driver, NIEON is always attentive and doesn’t get distracted or fatigued¹. The data showed that the Waymo Driver outperformed the NIEON human driver model by avoiding more collisions and mitigating serious injury risk in simulated fatal crash scenarios.
AIUI (I'm not on that team), a major challenge is getting good baseline data. Collision reports may not (reliably) capture that kind of data, and it's clearly subjective or often self-reported outside of cases like DUI charges.

Veserv · 14h ago
For which any such system must be assumed unsafe until proven safe and the burden of proof lies with the manufacturer to present sound, robust, transparent, third-party audited evidence.
You do not get to counter-argue: “What matters is the rate of cases per mile driven” without actually presenting that number with supporting evidence. Otherwise the only sound conclusion is the default presumption of non-safety.
In the case of Waymo, we have some tentative supporting evidence from this and other studies Waymo has run. However, that is still insufficient, even ignoring the lack of audits by non-conflicted parties, to strongly conclude Waymo is safer than a human. The evidence is promising, but it is only prudent to wait for further confirmation.
In contrast, Cruise was almost definitely not safer than a human driver.
In 2023, Cruise ADS cars drove 2,064,728 miles [1] and were involved in, by my count, 29 collisions with 5 causing injury [2], namely incidents on 2023-05-04, 2023-05-21, 2023-06-09, 2023-08-18, 2023-10-02.
That is ~72,000 miles per collision and ~400,000 miles per injury in contrast to the national human averages of ~500,000 per reported collision (which is non-comparable) and ~1,270,000 miles per injury (which is comparable). So, absent a more detailed analysis, Cruise ADS cars were ~3x MORE likely to be involved in a injury causing collision per mile.
Details and evidence matter in these discussions. Blanket rhetoric and optimism is not prudent when discussing new safety-critical systems.
To say that it is wholly insufficient to make any safety claims on publicly driven 50M miles, is ridiculous. At the very least, it appears sound, robust and transparent, and able to be validated.
Is Swiss Re a valid third party? They also address peer-reviewed and external validation in the above safety impact page.
I can understand being skeptical because of Cruise and especially claims made by Telsa, but there is a preponderance of supporting data for Waymo.
Given all of this evidence, you would still conclude Waymo is unsafe?
Veserv · 11h ago
I think I was quite clear on my position.

You are not making a distinction between concluding unsafe and not being able to conclude safe. It is standard practice to not presume safety and that positive evidence of safety must be presented. Failure to demonstrate statistically sound evidence of danger is not proof of safety. Failure to disprove X is not proof of X. This is a very important point to avoid fallacious conclusions on these matters.
To discuss your specific points. Yes, the data is promising, but it is insufficient.
Traffic fatalities occur on the order of 1 per 60-80 million miles. Waymo has yet to reach even one expected traffic fatality yet. They appear to be on track to doing better, but there is not enough data yet.
The reports Waymo present are authored by Waymo. Even the Swiss Re study is in cooperation with Swiss Re, not a independent study by Swiss Re. The studies are fairly transparent, they point to various public datasets, there are fairly extensive public reporting requirements, and Waymo has not demonstrated clear malfeasance, so we can tentatively assume they are “honest”. But we have plenty of examples of bad actors such as Cruise, cigarette companies, VW , etc. who have done end-runs around these types of basic safeguards.
Waymo operational domain is not equivalent to standard human operational domain. They attempt to account for this in their studies, but it is a fairly complex topic with poor public datasets (which is why they cooperated with Swiss Re) so the correctness of their analysis has not been borne out yet. When Waymo incorporates freeways into their public offerings this will enable a less complicated analysis which would lend greater confidence to their conclusions.
Waymo is still in “testing”. As their processes appear to be good, we should assume that their testing procedures are safer than should be expected out of actual deployment or verification procedures. That is not a negative statement. In fact, it would be problematic if their “testing” procedures were less or even equal in safety to their deployment procedures. That is just how testing is. You can and must apply more scrutiny to incomplete systems in use and prevent increased risks especially while under scrutiny otherwise you are almost certainly going to be worse off in deployment where there is less scrutiny. We have yet to see how this will translate out to deployment, so we will need to wait and see if safety while under test will appropriately apply to safety while in release. This is analogous to improved outcomes for patients in medical studies even if they are given the placebo because they just get more care in general while in the study.
Anyways, Waymo appears to be doing as well and honestly as can be determined by a third party observer. I am optimistic about their data and outcomes, but it is only prudent to avoid over-optimism in safety-critical systems and not accept lazy evidence or arguments. High standards are the only way to safety.

Assertion: "50M miles shows that Waymo is safer than humans".
Counter-point: "That's false because Cruise had an accident for which they were at fault".
OP: "The existence of a case or some cases where a self-driving car caused injury has zero value. What matters is the rate of cases per mile driven."
You: "You do not get to counter-argue."
Yes, they do. OP's point is valid. One can't refute the original assertion by citing one accident by another company. It's a logical fallacy (statistically speaking), and a straw-man (Waymo can't be safe, because other self-driving cars have been found at fault). The validity of the original claim has nothing to do with an invalid counter-claim.
> However, that is still insufficient, even ignoring the lack of audits by non-conflicted parties, to strongly conclude Waymo is safer than a human.
When you have a large, open, peer-reviewed body of evidence, then yes, that's exactly what you get to claim. To reject those claims because Waymo was involved is ad-hominem. It's not how science works. It's not how safety regulations or government oversight works. If you think it's insufficient, you can attack their body of work, but you don't get to reject the claim because they haven't met some unspecific and imaginary burden of proof.

I'm not sure what you're getting at here. By all accounts, Waymo operates more safely than a human driver. It's operated tens of millions of rides in several major cities over several years, hence all the useful data. There is absolutely nothing stopping the continued expansion of self-driving vehicles, Waymo or otherwise, and there are myriad factors moving it forward rapidly.
Veserv · 13h ago
I think I was pretty clear.
> You do not get to counter-argue: “What matters is the rate of cases per mile driven” without actually presenting that number with supporting evidence. Otherwise the only sound conclusion is the default presumption of non-safety.
I then pointed out how Waymo does present such evidence. But, if you applied that argument to Cruise you would be wrong. That demonstrates how that argument (when not presenting the numbers) can be used to support both good and bad and is thus a bad argument.
The correct argument when somebody points to anecdotes of bad outcomes is to present statistically sound data of good outcomes, not argue they did not present statistically sound data of bad outcomes thus you get to assume it is good.

Seems like it would more informative to link to an issue with Waymo instead of Cruise.
TulliusCicero · 12h ago
Note that even in the case you linked to, with Cruise, the initial accident was caused by a human driver.

You could also link to all of the people killed by self-driving Teslas. In my opinion, Teslas (especially) are bringing a bad name to the entire field.
vzaliva · 12h ago
One way to inteprent their data is that Waymo is LESS efficient protecting cyclists and motorcyclists compared to pedestriants. As a motorcycle rider I hope they will work to fix that gap.
floxy · 12h ago
What seems more likely, that Waymo is prioritizing pedestrian safety over cyclist safety? Or cyclists are much more likely to engage in risky behavior?
ndsipa_pomu · 10h ago
Maybe it's that cyclists are more likely to be trying to use the road and waymo is prioritising driving on the roads rather than the sidewalk?

While Waymo is good for safety, it is constantly collecting data not just from users, but from everyone nearby. The vehicles essentially function as mobile surveillance devices, recording bystanders without consent, with no clear policies on data use, retention, or oversight.
Waymo is like the most courteous, respectful driver you can possibly imagine. They have infinite patience and will always take the option which is the safest for everyone. One thing which really impressed me is how patient they are at crosswalks. When I'm jogging, a Waymo will happily wait for me to cross - even when I'm 10 feet away from even entering the crosswalk! I don't know if I even have that much patience while driving! I've had a number of near misses with human drivers who don't bother checking or accelerate for no reason after I'm already in the crosswalk. Can you imagine a Waymo ever doing that?
If I see a Waymo on the street near me I immediately feel safer because I know it is not about to commit some unhinged behavior. I cannot say enough good things about them.
Luckily, no one was hurt, and I generally trust a waymo not to plow into a pedestrian when it makes a maneuver like that. I also understand the argument that autonomous vehicles are easily safer on average than human drivers, and that’s what matters when making policy decisions.
But they are not perfect, and when they make mistakes, they tend to be particularly egregious.
Even setting aside the malicious SF stuff, Waymo's have enormous advantages over humans relying on mirrors and accounting for blindspots. I never have to be concerned a Waymo hasn't seen me.
I can't wait until the technology is just standard on cars, and they won't let drivers side-swipe or door cyclists.
Funnily enough that's exactly why I don't like them. Every time one rolls by me I know that tens of photos of me and even my 3D LIDAR scan get piled in to some fucking Google dataset where it will live forever :/
Their site is even proud of it: https://waymo.com/waymo-driver/ section titled “Keeping an eye on everything, all at once”
“The Waymo Driver's perception system takes complex data gathered from its advanced suite of car sensors, and deciphers what's around it using AI - from pedestrians to cyclists, vehicles to construction, and more. The Waymo Driver also responds to signs and signals, like traffic light colors and temporary stop signs.”
That being said, just speaking with some knowledge of current state: the scans don't live forever. At this point, all the data they collect is way too big to store even for a short period. They'll only keep data in scenarios that are helpful for improving driving performance, which is a tiny subset.
Personally identifiable information is also redacted.
You should probably be more worried about what gmail knows about you than Waymo.
Flock is the same way. For example here's the Flock privacy policy from one of SF's fine local shopping centers: https://www.stonestowngalleria.com/en/visit/lpr-privacy-poli...
> Video Clips captured by the LPR system will automatically be deleted after 30 days; although Images are deleted when no longer needed, the data obtained from the Images may be retained indefinitely. Should any information from the LPR Dashboard be needed to assist with a security or law enforcement matter, it may be retained indefinitely, in paper and electronic form, as part of the security file until it is determined it is no longer needed; in addition, it may be shared with local law enforcement who may retain it in accordance with their own retention policy.
If anyone can share a link to a similar IRL privacy policy for Waymo I would love to read it. The one on their website is conspicuously labeled Waymo Web Privacy Policy lol
For riders, there's the Waymo One privacy policy: https://support.google.com/waymo/answer/9184840?sjid=5254444...
Beyond that, https://support.google.com/waymo/answer/9190819?hl=en seems to be more relevant to your interests.
I'm pretty sure between traffic cameras and security cameras lots of commuters on th street are being filmed. With or without Waymos
It's not going to be stored forever.
That would be incredibly expensive.
Those cars are taking in TB of information each daily. Scale that to 10s of millions of cars.
It's just not going to happen.
Maybe an ultra compressed representation of you that shares maybe 1 bit in 1 weight somewhere in a NN will live forever.
Maybe.
Fear not, your images and recordings will get piled on somebody's dashcam to do as their heart desires.
I got a dashcam in my Camry recording front and back everytime i drive. I have no interest in preserving those images outside of an accident, but who knows what sommebody else will.
We have no expectations of privacy in public spaces and ultimately I would trust Googles IT security more than some dude with a dashcam
being concerned that a Waymo car took your picture isn't invalid, but man is it a tear drop in the rain of everything else the Googs is doing.
But car crashes are the third highest cause of death in the US (https://www.cdc.gov/nchs/fastats/leading-causes-of-death.htm). As a society, I think the benefit outweighs the cost in this case, and we can (theoretically) continue to make progress on privacy as a society. Seems like much more of a step forward than a step back to me
No, that says “Accidents (unintentional injuries)” as a category are collectively the third leading cause of death, and that category contains a lot of things.
CDC “Underlying Cause of Death” dataset sez… https://wonder.cdc.gov/ucd-icd10-expanded.html https://i.imgur.com/4PB0xyC.jpeg
- “Person injured in unspecified motor-vehicle accident, traffic” is the 50th leading cause of death at 0.4% of deaths.
- “Person injured in collision between other specified motor vehicles (traffic)” is the 108th leading cause of death at 0.2% of deaths.
(For cars that have both a normally-used electronic door open button and a manual emergency release (e.g. Teslas), the electronic button can use the car's existing cameras to detect cyclists first before actuating the door to open. This would be a trivial software change in the specific case of Teslas. The only thing I dislike about the Tesla setup though is that most non-owners are unaware of where the mechanical emergency release is; it is not obvious and not labelled.)
Tesla already has dooring prevention. If it detects a bicycle or something coming, it prevents you from opening the door the first time, and shows a warning. You can override it by trying to open it the second time, if you are sure.
https://www.reddit.com/r/teslamotors/comments/1gwjq4v/new_an...
Dooring people aside, what do you do if someone just leaves the door open when they leave their ride?!
Waymo needs to have staff in SF anyway to pick up cars that malfunction (flat tire, or just close the door).
Continue billing them for the ride and send an app notification or phone-call to their phone.
Other potential solutions: If the door is still not closed after n minutes, plead with passers-by, or offer a passing or nearby rider the chance to earn credit by closing the door.
They're probably too stupid to think like that, though.
Of course, passing costs to all insurance companies is really the same as passing it to all people paying insurance premiums, at which point you can just use tax money to get the same effect. At which point, it's probably easier to regulate it and have the cost passed to everyone buying a car.
I still remember the first time I went through a four-way stop intersection and saw a driverless car idling, waiting for its turn. It was weird and nerve-wracking. Now… I’d much prefer that to almost any other interaction at the same spot.
This has always bothered me about aggressive or impatient human drivers: they are probably shaving like 30 seconds off of their daily commute while greatly increasing the odds of an incident.
Now, when there's long stretch or when you have to go up hill, that's where the electric scooter begins to shine and makes the largest difference.
But people speeding, driving aggressively, driving anti-socially (by trying to speed past lines and cut in at the front), running lights and stops... this could be squashed forever, saving lives and ultimately making life more pleasant for everyone.
Ever since then my fear melted away. They see every direction, never blink, and are courteous and careful with pedestrians.
Might as well keep an automatic response even if it's not always useful.
People can have a stress-free commute to a nice house in the countryside and work in the cities. Because the car is electric, it will be inexpensive to run.
I can read on the subway, but while a 20 min subway ride is fine, an hour each way is still a lot, and a two hour train commute just doesn't leave much time in your life for doing social things.
Also, I think there's going to be a huge surge in in-demand AI buses. Rideshares will take people to a random spot, you'll wait 2 minutes for a predetermined seat on a specific bus, and then switch to a rideshare van for the last 5 minute drive to your office in the city.
It's just going to be so much cheaper. With economies of scale and urban congestion pricing, you'll have to choose between dropping $45 on a dedicated hour-long door-to-door car trip, or $6 for the car-bus-van version which is only 20% slower anyways.
OTOH, if I'm in a decent-sized car (minivan?) for 45 minutes+, I can get work done. I can then stay less time at work.
You're clearly wrong.
> Late-stage capitalism will find ways to make it cost exactly as much as driving your own car.
Late-stage capitalism is a defunct theory based on Marxism.
Real, actual capitalism results in competition which drives prices down, as long as there are two or more competitors and antitrust law is enforced. Which is generally the case.
And in the case of monopolies like city buses, cities set prices directly in response to democratic pressure. By your argument, NYC subways ought to be $25 a ride... but they aren't.
(And that was not the only close call I had with that geezer at that corner.)
If you drive a lot (like the person in the countryside) the car that is there when you want to is worth owning vs a shared car that you might have to wait for. Plus by owning the car you can just leave your golf clubs in the trunk.
If you can stand being in a used car you will discover that shared cars are all more expensive just because at the first sign of cosmetic wear they get rid of it while seats that have been sat in a few times are still good enough for many more years. (unless you almost never drive anyway)
Because of the above I don't see much growth in the shared car market. There will be some because there are people who don't have parking, people who don't drive much, and people who demand a new car that they don't otherwise care about. However the vast majority of people will still own their own car.
I've now had it happen twice that a car will fully blow through an intersection because they know a Waymo will slam on the breaks to avoid a collision. They basically abuse the car's reflexes.
Also in any sort of situation where the Waymo is being very cautious the biggest danger is the impatient people behind the Waymo who will break the law to go out and around it.
I imagine the weirdness of the situation (legal left on red) triggers it's "creep forward so I can see" logic but it definitely shouldn't be blocking a busy crosswalk there when there is little to know chance it will be able to turn AND peds from both sides.
Besides, this is a study on Waymo probably influenced by them too to publish on their blog.
If they keep up the slow and steady improvements and roll outs to cities worldwide it’s hard to imagine my one year old ever needing to drive a vehicle.
Looking forward to this future.
Really excited for autonomy to become more and more common place. People drive more and more like distracted lunatics these days it seems
Humans drive in all weather conditions on all types of roads and also many types of personal vehicles of varying ages and conditions.
Waymo is limited to few specific locations with decent roads and does not drive in poor weather and is limited to a relatively large and safer expensive SUV that is maintained professionally in a fleet.
Studies like this rarely account for such factors , they are compare optimal conditions for self driving to average conditions for humans.
Even if waymo was better when accounting for these factors , if it was much worse in the conditions humans typically are expected to drive [1] they self driving is still less safe than humans on average .
A better comparison could be with professional taxi drivers for the same city (not Uber or Lyft).
I wouldn’t be surprised if Waymo is either on par or poorer than this group .
[1] no study will ever show this as they wouldn’t be able to trial it under those conditions if it is not safe enough
If you've been in both a human drive cab and a Waymo, you'd definitely not say this. I see cabs have accidents all the time. Never seen a Waymo have one.
Also, being in a Waymo feels much safer than a human driven car, even my own when I'm driving!
I highly doubt taxicabs are safer than Waymos.
In fact, here is some data:
Over every 1 million miles driven, there are 4.6 cab crashes, 3.7 livery car crashes, and 6.7 crashes with private cars. And according to Waymo, they have 2.1 crashes per million miles.
> Waymo 2.1 crashes
The numbers become much less 80+% plus claim in the article as you remove factors. It comes closer to 30% with professional drivers.
Livery car is still not always well maintained a high sitting SUV with better visibility[1], perhaps with all these factors included if it is 20% better it is impressive technical achievement for sure, but not going to create headlines anywhere.
The point is the methodology is not as objective as it could be, and this is biased/selective claim, not that self driving cannot be better than humans.
[1] Also there is major difference in the price point between Waymo and Livery cars, I cannot say how it will influence rates but the different rates means different class of clients using at different times of day/night to different locations that needs to be normalized for.
The % matters because it is close enough excluding these factors, so we can not definitely say it currently better than humans yet, close but not conclusively so.
That is not a argument against them. It is a simple function of economics, i.e. as long as it better than Lyft/Uber(they are already) that is the price point that Waymo operates at, so it is safer for most users and easy choice to make.
However if you can afford and regularly use high quality private livery car services then the data has to be lot clearer to make the switch.
the study is comparing Waymo to accidents occurred in the same cities where Waymo operates, and my understanding is that Waymo drives 7 days a week, 24h a day in those cities, so same roads, same weather. Seems a legit comparison
Seems they intend to come to Washington D.C. next year, which does get a pretty wide gamut of weather.
There have been promising progress and there have been hints of a New York trial soon, but it it well known that self driving cars have not done large scale trial in cities with bad weather.
[1] Yes, I am aware SF gets a bit of bad weather with fog and rain but not nearly not as much to make driving quite unsafe like somewhere that gets a feet of snow in 24 hours in winter, and likely promixity to engineering HQs and favourable regulatory climate influenced the SF choice.
Uber/Lyft drivers are strongly incentivized to drive as quickly and aggressively as possible.
The individual drivers are trading risk for cash.
A company like Google isn't going to make that trade because it's actually the wrong trade across millions of hours.
https://economics.uchicago.edu/news/study-finds-gender-pay-g...
So a fairer comparison would be contrasting Waymo rides to trips conducted by the Ultra Safe Even If It's Slower Chauffeur Company.
no, comparing them to real alternatives is the fair comparison. that they've got their settings tuned in favour of safety stats is the whole point, not something that you should be trying to factor out of the comparisons.
For now, yes. My point is that there's very often big gap between "how safely does it work in a lab when the people running it are trying to play up its safety" versus "how safely will X actually work once we start using it everywhere."
Manually-driven vehicles could be a lot safer if they were being prototyped under strict guidance as well!
If we want self-driving cars to retain the same safety later, there needs to be something which prevents humans from flicking the safety-versus-speed dial a little bit over and over in order to make quarterly earnings projections.
But they aren’t. These are. Planes could be less safe if pilots flew them into cliffs on the regular, but they don’t and so are not.
Uh, yes, you're kinda repeating my thesis, and two copies don't cancel each other out.
> Planes could be less safe if pilots flew them into cliffs on the regular, but they don’t and so are not.
I don't understand what you're trying to convey with this tautology.
_________
Imagine two fleets of cars/planes/whatever with utterly identical equipment and expertise. The only difference is that for one of them, the management is being pressured by politicians to demonstrate a high degree of safety.
For that scenario, wouldn't you agree that the better-safety comes from temporary external cause? And also agree that the better-safety is unlikely to persist long after the incentive disappears?
[TLDR] Some portion of Waymo's safety-stats are due to the investor/regulatory context in which it currently operates, rather than the underlying technology; the effects of that portion will not be permanent; this should affect how we do comparisons.
We don’t need to. I could also imagine every human driver is always drunk. But those are suppositions. You’re comparing actual and hypothetical risks.
Your ancestor: "No, we don't need to. I could also imagine them underwater. Those are suppositions. You're comparing actual and hypothetical falling."
*headdesk*
____
How about this: Which parts of the final TLDR do you disagree with?
Also, if you want to include the speculation that they'll make their cars drive more aggressively, you should also include the speculation that the technology will become better and the driving tech will become even safer than they are now.
Good. I don't want my kid who's crossing an intersection to be endangered by an Uber driver that you paid $30 to go extra fast. Nothing like externalizing your poor planning skills onto others.
IMO they already won. The amount of stupid things you see people do here while driving is astonishing, so many people are not paying attention and looking at their phones.
I used an Uber on the way here and the car was dirtier while the service was identical (silent ride, got me where I needed to go.)
I’ve also been stuck in a Waymo that couldn’t figure out its way around parked buses, so they have edge cases to improve. But man does it feel like I’m living in the future…
To be fair, the fact that Waymos are fancy clean Jaguars is kind of ancillary to the main technology. The tech is currently expensive, so they are targeting the luxury market, which you can also get on Uber if you select a black car or whatever. The people willing to pay for that are less likely to make messes, and the drivers put more effort into frequent cleanings.
Once the tech becomes cheap, expect the car quality and cleanliness to go down. Robocars do have some intrinsic advantages in that it's easier to set up a standard daily cleaning process, but they will still accumulate more garbage and stains when they are used by a broader cross section of the population and only cleaned during charging to reduce costs. (Of course, cheaper and more widely accessible tech is good for everyone; if you want a immaculate leather seats cleaned three times a day, you'll generally be able to pay for it.)
Cleanliness doesn't seem that related to how expensive the tech is either - if anything it would only go down if it ceased to affect willingness to pay. As it stands, clean cars are important to their customers. If usage increases, cleaning can ostensibly increase too, no?
Regular taxis around here are also liveried fleet vehicles. Especially the very large providers: if I summon a taxi cab, I know for sure its make and model, and its paint job will clearly indicate it's on-duty as a taxi cab. You don't understand how incredibly important this is sometimes.
For the simple yet panic-inducing task of strapping on my seat belt: I can do it in seconds with a liveried vehicle, because I know exactly what to expect. In a rideshare like an Uber, every time a car arrives, it is a new make, new model (I swear to god what the fuck is a "Polestar"???) and the owner might have wrapped on some crazy aftermarket seat covers, and finding the seat belt and its mating latch is a huge drama. I've taken to leaving the passenger seat open, until I can get the belt safely latched, because otherwise the driver will promptly take off, and panic will increase 3x as the vehicle is moving and I can't find the seat belt.
Other than that, the liveried vehicles are easier to maintain; they're easier to keep clean; they're much better for brand recognition. Hallelujah for Waymo!
* Waymo vehicle creeping into the pedestrian crosswalk (while the pedestrians had right of way to cross), which caused someone to have to walk around the car into the intersection ahead of the Waymo.
* Waymo vehicle entering a dedicated bike lane and practically tailgating the bicyclist that was ahead of it.
These might be safer than human drivers in aggregate and normalized by kilometer driven, but they drive like humans — greedily and non-defensively. I wouldn't want one these anywhere near a high-pedestrian traffic area ever, and I feel the same about human-driven cars, too.
In California, California Vehicle Code § 21209(a)(3) expressly permits a motor vehicle to enter a bicycle lane “to prepare for a turn within a distance of 200 feet from the intersection” -- among other cases. (The vehicle must yield to cyclists in the lane.)
Much of San Francisco is a "a high-pedestrian traffic area" and Waymos operate in those areas constantly and more or less flawlessly. As someone who lived carless in SF for nearly 15 years, I see nothing but upside from more Waymos and less human drivers on those busy streets.
I know it can seem discourteous to cyclists, but it really is the smarter way.
We also know that in North America that the municipal services skimp on grade separation for bike lanes for budget and political reasons. I did bike in San Francisco when I lived there, and these non-shared colored lanes never ever felt safe.
I can guarantee that if you leave your North American context for a couple of years and come back to it you'll find CA Vehicle Code § 21453 unsatisfactory.
Human drivers often race when in a platoon— not even on purpose it’s just an instinct to go as fast or faster than other cars which has a feedback effect to increase platoon speed.
Waymos, following the exact speed limit, don’t do this. On 1 lane streets they literally set the platoon pace to the legal speed limit.
The effect of this is hard to study and quantify but it’s a real and positive impact of self driving cars on city streets. Haven’t seen research on this topic yet.
On some roads, however, it is a massive safety issue, and everyone is driving unsafely because the road is designed badly for its intended purpose. (So-called “stroads” are the canonical example.)
You don't drive 25 on residential roads, because you know this to be true. Neither do I, nor does anyone else.

(I don't work on that team, but I've noticed a few comments that would be better served with their own analysis on top of the available data)
I am not convinced that public testing of such services is safe, let alone commercial service. One cannot punish a self driving vehicle in any meaningful sense. Corporate incentives vs the public commons, is a general concern that cannot be sweettalked away.
The metaphors about human drivers recording you also seem like reductio ad absurdum.
puff pieces like this should not be well received on HN or it discredits any pretence at separation of concerns with regards to HN and ycomb.
There are currently over a million fatalities from road traffic crashes every year, being the leading cause of death for the 5-29 year age group[0].
I'd claim that inaction is unacceptably dangerous/deadly here and that, to minimize deaths, we need to be aggressive in trying out and pushing forward potential solutions.
> One cannot punish a self driving vehicle in any meaningful sense.
The goal of punishment for driving offenses is, in my eyes, largely about reducing unsafe behavior - not just to make someone suffer. Fines/incentives for manufacturers and fine-tuning of models based on incident data should fulfill this purpose.

Blog post for the paper: https://waymo.com/blog/2022/12/waymos-collision-avoidance-te...
The correct answer is almost always to hit the brakes. Not to swerve. And Waymo will hit the brakes earlier than you or me.
Hard to say for certain, but it looks like just braking probably wouldn't have avoided the collision.
Also, shifting into neutral is really only a thing for old vehicles without ABS/ESC. In modern vehicles, you let your foot off the gas slowly.
This is only true with 2WD and no automatic stability control, and if you’re going down a slope. For every other case, ABs will out perform in snow and gentle braking will evenly distribute traction force with stability control doing microsecond evaluations.
Stability control is tied to power in all modern systems.
As someone who grew up BEFORE ABS, drove in the winter (in Canada), including first winter owning my own car with sport tires because I couldn't afford winter tires, spun / slid a few times even with top-of-the-line winter tires, etc.
ABS is a game changer in the snow. I used to go to an empty parking lot every winter during early snowfalls to play around and skid, start/stop, etc. Even EARLY ABS ('94 VW) means that 98% of the time (IMHO), the answer even in snow/ice is "slam on the brakes". Sure, you might have a few percent longer stopping distance than an expert who can do threshold braking - are you an expert? And the fact that you don't lose control of the steering is a huge advantage.
(You also only get into this scenario when your stopping distance is shorter than your reaction time and perception length. Something automated drivers can manage better than humans.)
do you also maintain a long following distance when there's a car right next to you in the next lane? I try to, because I don't want to stay in someone's blind spot, but sometimes it's not really possible to fall back.
Perhaps you mean the far more common scenario when the car in the next lane simply decides to merge into yours? Nothing about that is random[1] and the response in 90%+ of cases is just to let off the gas for a few seconds. That's it.
[1]: In most cases, it's because your lane is open and theirs is about to be backed up. You'd want to switch lanes too, so it really shouldn't be surprising they do.
The rest are mostly people realizing at the last second they want to turn right/left at an upcoming intersection (or highway exit). Again, predictable.
You're safer hitting them head on while aggressively braking than attempting a microsecond swerve.
Exactly, this is the situation I am mostly talking about.
If it’s 1989 and you don’t have ABS, yes. Otherwise, swerving is a gamble [1]. If you don’t have time to stop, you physically don’t have time to evaluate and choose a right or left swerve. You’re trading the certainty of a head-on collision with whatever is in front of you against the uncertainty of what’s to the right or left, compounded with all the fun that comes with a side/tumbling collision and increased risk of not hitting a car.

> I agree though that most people's extinct would be to brake. Mine never has been though.
...
You operate a motorized vehicle and your first instinct when seeing anything dangerous ahead is to do something other than braking?
- How seldom these scenarios come up for human drivers is a huge disadvantage for them. For self driving, it doesn't matter, the cars' reactions can be simulated in arbitrary scenarios as many times as needed, so even the rarest of scenarios can be ensured to be handled properly.
- There's nothing special about the decision to swerve vs to say, brake. I'd expect self driving cars to not need to swerve nearly as often because the need to swerve probably only ever exists due to excessive speed and/or poor following distance to the vehicle ahead.
> It's happened to me about 2-3 times and I've always made the "(assumedly) correct" split second swerve decision.
Easy question: Did you make that decision with full awareness that you would not end up in a collision path with another vehicle by swerving? Oops.
Even if you did, how many drivers do you think would "instinctively" swerve into another lane and get hit by an oncoming vehicle because they do not maintain constant situational awareness around their vehicle? The majority, at least.
I feel also that the car having a far better experience of its kinematics / dynamics / features is also a huge advantage - see the good old drifting parallel parking videos.
After that there is the concern about computing reaction time. Can it get stuck hesitating? Clearly the cars hesitate a lot in generally safe places. But we have seen some videos already of a Waymo very smoothly dodging someone running out from in between cars (they were already tracked), and someone mentioned a scooter incident. Hopefully we'll see more videos of emergency responses.
Another comment mentions "r/waymo or r/selfdrivingcars for lots of videos of Waymos avoiding objects."
The Waymo doesn't have to swerve as much as a human because it can see a mile away and never blinks, and it knows that the right thing to do in every swerve-worthy situation is to slam on the brakes to take the energy out of the event. It also drives around with the brakes pre-pressurized because it isn't trying to compensate for the fact that its control system is partially made of meat. Anyway you can go to r/waymo or r/selfdrivingcars for lots of videos of Waymos avoiding objects.
It was a funny ad at the time. Unfortunately based in reality more and more these days.
But that's why you have peer review, further studies from different authors perhaps on competing methods that point out some flaws in your approach, etc.
If a $10,000 investment reduces the chances of a serious accident by 90%, the corresponding reduction in insurance rates might have a payoff within a few years. Especially if adoption starts to push rates up for customers who don’t automate. I can’t take a taxi everywhere, but I’d sure like it if my car drove me everywhere and did a better job than me at it too.

Don't get my wrong, I'm hoping it is soon. However they have a lot of work left.
Of course, safety first, so they should take their time and not rush things...
Is having insurance not legally required? Do they just pay out when there's an accident where they injure someone?
When I was much younger, I worked for a couple companies that had (what I would consider) large fleets of vehicles, and they all were insured through an insurance company. I guess I just assumed that's how it was. I wasn't aware self-insuring was a possibility. Thanks.
Often self insure means they still pay an insurance company to handle the paperwork, but when there is a claim the company pays it.
[1] Edit - I meant 5% not half, I was on the train and very frustrated with these comments. (not yours, though it seems bad faith to say "not remote driving" when I said "problem solving." The problem has always been the 1-5% of driving which truly requires sophisticated intelligence, that's why the oversight is there.)
Every Lyft driver I've spoken to drives because a) they like driving b) they like choosing their own hours and c) they don't want a boss. Telling them to go into an office for an 8 hour shift with a manager is not gonna work, they will find something more appealing. It's a different kind of employee. (I would enjoy that line of work but I would hate to drive for Uber, way too stressful.)
I emphasized that Waymo staff does not drive vehicles remotely, because this persists as a common misconception.

HN has a credibility problem here.
Well considering this sensor package...

Or all things Elon bad?
So is the accident rate lower because people are forced to be more attentive during FSD? Or is it genuinely lower (i.e, if you took out the driver, would there be less accidents)? To be fair, I'd still wager that yes, FSD is probably statistically way better than the average driver.
Maybe some combination of miles per intervention + accident data would give more insights into that.
As they become the monopolist, like they always do, watch how they’ll run the age old playbook to destroy the market and then hike prices.
I’m not against self-driving cars. I’m against self-driving cars owned by a few megacorps, that will have even control and surveillance capabilities in addition to what’s already in your pocket.
Perfect is the enemy of the good. This sort of technological NIMBYism is, in practice, opposition to self-driving cars and their safety benefits.
Then it'd be like finding a cure for cancer, for people aged 0 - 40, who die as much in auto accidents as they do of cancer
this is blatantly obvious and unacceptable.
the site rules prohibit accusations of astroturfing but that is precisely what is going on here.
precisely no sf programmers were convinced, either.
this site had better be concerned with future legitimacy and not being seen as a puppet of specific corps like waymo.
They can definitely do better when taking left turns. I've seen situations where Waymo depends on the oncoming drivers to slow down.
A "self-driving" car can cause the same accident but gain advantages over a human driver that the person ultimately responsible is no longer held to the same set of laws.
This seems to undermine foundations of law, placing the owners of those assets into a different legal category from the rest of us.

CDC “Underlying Cause of Death” dataset sez https://wonder.cdc.gov/ucd-icd10-expanded.html https://i.imgur.com/4PB0xyC.jpeg
- “Person injured in unspecified motor-vehicle accident, traffic” is the 50th leading cause of death at 0.4% of deaths.
- “Person injured in collision between other specified motor vehicles (traffic)” is the 108th leading cause of death at 0.2% of deaths.
0.4% and 0.2% sound low, but make up for ~110,000 deaths. Spread across a 5 year period does indeed equal “tens of thousands” every year.
But, more importantly, you missed a bunch of relevant categories:
V89.2 (Person injured in unspecified motor-vehicle accident, traffic) 80,434
V87.7 (Person injured in collision between other specified motor vehicles (traffic)) 29,982
V09.2 (Pedestrian injured in traffic accident involving other and unspecified motor vehicles) 27,934
V03.1 (Pedestrian injured in collision with car, pick-up truck or van, traffic accident) 15,129
V43.5 (Car occupant injured in collision with car, pick-up truck or van, driver injured in traffic accident) 9,810
V29.9 (Motorcycle rider [any] injured in unspecified traffic accident) 8,410
V29.4 (Driver injured in collision with other and unspecified motor vehicles in traffic accident) 7,688
V47.5 (Car occupant injured in collision with fixed or stationary object, driver injured in traffic accident) 6,379

V27.4 (Motorcycle rider injured in collision with fixed or stationary object, driver injured in traffic accident) 3,504
The same of course applies to self-driving cars; they are literally cars driven by software, of course you need to do a root cause investigation every time to rule out that it's not a bug in the software that will kill another person (and many after) when the next car happens to go down that rare branch of the system. It's embarrassing to see that the people that call themselves engineers at these companies have not held their work to this standard, and are instead publishing glossy brochures making whacky statistical arguments.
I've personally read through the root cause reports for most of the notable AV accidents. They're not always quite as intensive as aerospace, but I'd be hard pressed to describe any of them as wacky statistical arguments.
Obviously most of those reports aren't public, but I'm assuming you also have industry access.
50% of fatalities involve alcohol or drugs and are often single vehicle accidents.
25% involve youth or inexperience.
15% involve motorcycles.
15% involve pedestrians.
What I really need to see is a complete breakdown of every accident a Waymo has had. Then I can start to compare their actual performance to the previously known outcomes.
No, that's not how statistics works.
The percentage data's accuracy depends mainly on the number of incidents recorded (and somewhat on the rate of incidents). But the percentage of the whole is completely irrelevant.
If you are basing something on 10 incidents but it's 50% of the total, it's still terrible accuracy.
Whereas if you are basing something on 100,000 incidents but it's only 0.1% of the total, it's still going to be quite accurate, assuming the incidents come from the same overall distribution.
If the user base of "waymo riders" and "everyday drivers" does not match then you're not sampling what you think you are.
The ratio of 3.2 trillion to 56.7 million, which is already incredibly generous to Waymo's position, is 5 orders of magnitude in difference. So any calculations from Waymos data are going to be insanely inaccurate and not something you can extrapolate from.
The main, and most obvious case, evidenced by this, is Waymo does not operate where snow falls. Human beings do.
We're missing so much of the picture I don't think you can say Waymo's are 75% less accident prone, or 80% less likely to hit a pedestrian. Those are just nonsense numbers.
You could still say you care about snow driving and want to see that comparison, but it doesn't mean the claims in this paper are wrong.
Your third sentence doesn’t follow from your first two. On what grounds do you draw this conclusion?
This suggests that Waymo is cutting traffic fatalities by 50% (per million miles) right off the top.
Drunk people being known for having exceptionally poor judgement and self awareness.
It suggests that they _could_ cut fatalities by that much. Then again, a whole new mode of accident, where the inebriated decide to step out of a moving vehicle and injure themselves that way.
This is a dynamic system where human decisions are never fully removed from the loop.
If I understand correctly, you believe that the advent of self-driving cars will cause passengers to voluntarily exit a moving vehicle? That sounds like absolute nonsense with no basis in reality.
Why would they need to be in a self-driving vehicle to do that?
> Building on that, the Collision Avoidance Benchmarking paper presents a novel methodology to evaluate how well autonomous driving systems avoid crashes. The study, which to our knowledge is the first of its kind, introduces a reference model that represents an ideal human state for driving—the response time and evasive action of a human driver that is non-impaired, with eyes always on the conflict (NIEON). Put simply, unlike an average human driver, NIEON is always attentive and doesn’t get distracted or fatigued¹. The data showed that the Waymo Driver outperformed the NIEON human driver model by avoiding more collisions and mitigating serious injury risk in simulated fatal crash scenarios.
(From https://waymo.com/blog/2022/09/benchmarking-av-safety)
AIUI (I'm not on that team), a major challenge is getting good baseline data. Collision reports may not (reliably) capture that kind of data, and it's clearly subjective or often self-reported outside of cases like DUI charges.
You do not get to counter-argue: “What matters is the rate of cases per mile driven” without actually presenting that number with supporting evidence. Otherwise the only sound conclusion is the default presumption of non-safety.
In the case of Waymo, we have some tentative supporting evidence from this and other studies Waymo has run. However, that is still insufficient, even ignoring the lack of audits by non-conflicted parties, to strongly conclude Waymo is safer than a human. The evidence is promising, but it is only prudent to wait for further confirmation.
In contrast, Cruise was almost definitely not safer than a human driver.
In 2023, Cruise ADS cars drove 2,064,728 miles [1] and were involved in, by my count, 29 collisions with 5 causing injury [2], namely incidents on 2023-05-04, 2023-05-21, 2023-06-09, 2023-08-18, 2023-10-02.
That is ~72,000 miles per collision and ~400,000 miles per injury in contrast to the national human averages of ~500,000 per reported collision (which is non-comparable) and ~1,270,000 miles per injury (which is comparable). So, absent a more detailed analysis, Cruise ADS cars were ~3x MORE likely to be involved in a injury causing collision per mile.
Details and evidence matter in these discussions. Blanket rhetoric and optimism is not prudent when discussing new safety-critical systems.

Waymo releases its safety data: https://waymo.com/safety/impact/, which is backed by public reporting requirements.
To say that it is wholly insufficient to make any safety claims on publicly driven 50M miles, is ridiculous. At the very least, it appears sound, robust and transparent, and able to be validated.
> https://waymo.com/blog/2024/12/new-swiss-re-study-waymo
Is Swiss Re a valid third party? They also address peer-reviewed and external validation in the above safety impact page.
I can understand being skeptical because of Cruise and especially claims made by Telsa, but there is a preponderance of supporting data for Waymo.
Given all of this evidence, you would still conclude Waymo is unsafe?

You are not making a distinction between concluding unsafe and not being able to conclude safe. It is standard practice to not presume safety and that positive evidence of safety must be presented. Failure to demonstrate statistically sound evidence of danger is not proof of safety. Failure to disprove X is not proof of X. This is a very important point to avoid fallacious conclusions on these matters.
To discuss your specific points. Yes, the data is promising, but it is insufficient.
Traffic fatalities occur on the order of 1 per 60-80 million miles. Waymo has yet to reach even one expected traffic fatality yet. They appear to be on track to doing better, but there is not enough data yet.
The reports Waymo present are authored by Waymo. Even the Swiss Re study is in cooperation with Swiss Re, not a independent study by Swiss Re. The studies are fairly transparent, they point to various public datasets, there are fairly extensive public reporting requirements, and Waymo has not demonstrated clear malfeasance, so we can tentatively assume they are “honest”. But we have plenty of examples of bad actors such as Cruise, cigarette companies, VW , etc. who have done end-runs around these types of basic safeguards.
Waymo operational domain is not equivalent to standard human operational domain. They attempt to account for this in their studies, but it is a fairly complex topic with poor public datasets (which is why they cooperated with Swiss Re) so the correctness of their analysis has not been borne out yet. When Waymo incorporates freeways into their public offerings this will enable a less complicated analysis which would lend greater confidence to their conclusions.
Waymo is still in “testing”. As their processes appear to be good, we should assume that their testing procedures are safer than should be expected out of actual deployment or verification procedures. That is not a negative statement. In fact, it would be problematic if their “testing” procedures were less or even equal in safety to their deployment procedures. That is just how testing is. You can and must apply more scrutiny to incomplete systems in use and prevent increased risks especially while under scrutiny otherwise you are almost certainly going to be worse off in deployment where there is less scrutiny. We have yet to see how this will translate out to deployment, so we will need to wait and see if safety while under test will appropriately apply to safety while in release. This is analogous to improved outcomes for patients in medical studies even if they are given the placebo because they just get more care in general while in the study.
Anyways, Waymo appears to be doing as well and honestly as can be determined by a third party observer. I am optimistic about their data and outcomes, but it is only prudent to avoid over-optimism in safety-critical systems and not accept lazy evidence or arguments. High standards are the only way to safety.
Counter-point: "That's false because Cruise had an accident for which they were at fault".
OP: "The existence of a case or some cases where a self-driving car caused injury has zero value. What matters is the rate of cases per mile driven."
You: "You do not get to counter-argue."
Yes, they do. OP's point is valid. One can't refute the original assertion by citing one accident by another company. It's a logical fallacy (statistically speaking), and a straw-man (Waymo can't be safe, because other self-driving cars have been found at fault). The validity of the original claim has nothing to do with an invalid counter-claim.
> However, that is still insufficient, even ignoring the lack of audits by non-conflicted parties, to strongly conclude Waymo is safer than a human.
When you have a large, open, peer-reviewed body of evidence, then yes, that's exactly what you get to claim. To reject those claims because Waymo was involved is ad-hominem. It's not how science works. It's not how safety regulations or government oversight works. If you think it's insufficient, you can attack their body of work, but you don't get to reject the claim because they haven't met some unspecific and imaginary burden of proof.
> You do not get to counter-argue: “What matters is the rate of cases per mile driven” without actually presenting that number with supporting evidence. Otherwise the only sound conclusion is the default presumption of non-safety.
I then pointed out how Waymo does present such evidence. But, if you applied that argument to Cruise you would be wrong. That demonstrates how that argument (when not presenting the numbers) can be used to support both good and bad and is thus a bad argument.
The correct argument when somebody points to anecdotes of bad outcomes is to present statistically sound data of good outcomes, not argue they did not present statistically sound data of bad outcomes thus you get to assume it is good.
