Show HN: Report idling vehicles in NYC (and get a cut of the fines) with AI

79 rafram 95 6/22/2025, 5:06:51 PM apps.apple.com ↗
New York City has this cool program that lets anyone report idling commercial vehicles and get a large cut of the fines [1]. It's been in the news recently [2].

I've filed a few reports, and I found the process frustrating and error-prone. The forms are fiddly, there's way too much information that needs to be copied down from the video by hand, you have to use a third-party app to take a timestamped video and a different app to compress it before uploading, and approximately none of it can be done on your phone — the device you probably used to record your video in the first place.

I built Idle Reporter to make filing complaints into a five-minute process that you can do entirely from your phone.

Idle Reporter uses AI to automatically extract all the required information and screenshots from the video and fill out the form for you. It compresses your video, adds the required screenshots, and uploads the whole thing to DEP. All you have to do is log in, give it a final check, and submit.

The AI features cost me money to run, so I put those behind a subscription ($5.99/month, which can pay for itself after a single report). There's a one-week free trial so you can test it out. All the other features — including a fully-featured timestamp camera, which other apps charge for, and an editor for filling out the forms manually and submitting in a single step — will be free forever, as a service to the community.

The app is iOS-only for now — part of this was an exercise in learning SwiftUI in my spare time.

Check it out on the App Store and let me know what you think!

This is a phenomenal application of how fine-based bounties can be used to rapidly improve compliance with the law. Incredible work. I would absolutely use this if I lived in NYC; I'll recommend it to my friends there.

Within the last year or so, I discovered my city’s 311 app, which I’ve become addicted to. I don’t drive, so I’m always walking around the neighborhood, and got in the habit of always reporting graffiti, dumping, illegally parked cars, etc.

This had inspired me to try and make a few apps for civic use, but I discovered that many of the accessible web tools for my city have rules against bots. For example, the city maintains a list of locations and dates where parking is temporarily restricted for short term things like construction, but I can’t scrape it.

I really wish that the government (at any level) made more serviced and data available as APIs or digital formats. The government is usually bad at building/buying websites and services, and I’d have done it for free (or for $0.99 on the App Store).

Amazing !

Decentralizing traffic enforcement is a win-win. Bravo to NYC for opening this sort of program and OP for turning it into an "efficient free market".

Will try it out soon. Bookmarked.

It's not a win-win.

Look at China as a perfect example of what happens when you apply this idea at scale.

Win-win for who exactly? Maybe we need to decentralize and AI-accelerate construction permit reporting too. Your backyard fence looks DIY and not up to code and your porch light looks like a fire hazard.

They're trialing something like that in France. There's a project that uses machine learning on aerial photography databases to search for objects in peoples' backyards, for enforcement,

Most cities have ways for neighbors to report things like this.
dale_huevo · 1h ago
Yes, and they're almost exclusively used by the worst type of vindictive chickenshit humans imaginable. I've known people affected by this, whose evil neighbors used 311 as a weapon because they simply didn't like them, and caused them tens of thousands of dollars in forced unnecessary renovations not to mention stress, for trivial violations that are widely ignored.

Absolutely this should be reported.

It used to be that as long as the vehicle was on the same block as a school or park, you only had to take a one-minute video (versus three-minute). Now there are some annoying documentation requirements if you want to submit a shorter video.

Doesn’t impact the overall usefulness of the program very much IMO — I just didn’t add special handling for school/park reports like I would’ve before they made that change.

matsemann · 52m ago
Man, I wish my city would make it possible to report drivers breaking the law. My big issue is cars parking in the cycle lanes. 1830 cars got fined for that in my city in total in 2024. Aka 5 a day. As a single cyclist I see more cars parked in cycle lanes every day on my commute than all those hundred officers give tickets to in total..
cosmic_cheese · 35m ago
What I’d like to see is hard separation of roads and bike lanes. As a cyclist, nothing but a line painted on the road makes me feel unsafe, as a driver it’s difficult to not get nervous when passing a cyclist in the lane, and culturally drivers are generally favored over cyclists which results in things like parking in bike lanes not being adequately enforced. All these things would be solved by bike lanes being fully independent from the road.
josephcsible · 1m ago
> What I’d like to see is hard separation of roads and bike lanes.

That's a great idea, as long as the hard separation goes both ways with bikes no longer being allowed in car lanes.

Nice. Pricing seems a bit steep for occasional use; does iOS make it easy to do micro-transactions with Apple Pay? (I get the dev may be trying to put bread on the table with this, which is also fine…)
rafram · 2h ago
That's a fair point. I have to see how the AI costs stack up, since heavy use can run up the bill pretty quickly with video inputs, and all subscriptions come with unlimited usage.

Wouldn't it make more sense to charge per report?

As a user I’d be happy to pay $5 for a bundle of credits and just top up whenever it runs out.

And as you say you don’t want to be in the position where a whale costs you $50 by submitting a crazy number of requests.

Maybe these are big-scale problems though :)

georgeburdell · 45m ago
Wish my California city had this attitude that you can report people via an app. So many offenses “run with the driver, i.e. they will not prosecute unless a cop sees it happening and positively identifies the driver. They won’t even prosecute red light running from a video with the license plate clearly visible.
a5c11 · 1h ago
Since you've mentioned it, that'd be great to give some details regarding the AI mechanism you used. I really find that trend of hiding everything behind "The Divine AI" off-putting. What exactly AI does in the context of the application?
theptip · 2h ago
I like the general idea, and I’ve been surprised this hasn’t taken off elsewhere, eg citizen videos for traffic violations like blocking intersections, it seems these should be ROI positive for the city to implement (lower enforcement costs, more ticket revenue).
crote · 1h ago
Some countries are already doing this, for example Vietnam and China.

I recall reading about it years ago because some enterprising individuals decided that the revenue from catching random violations in-the-wild wasn't enough, so they started to deliberately create dangerous situations, where breaking a traffic law (which would then be recorded and submitted for a reward) was the only safe option for the victim. Unfortunately I haven't been able to quickly find a source to back this up.

hiAndrewQuinn · 4m ago
This is why optimal policy design has the fines get paid directly from the violator to the reporter. That brings its own quirks, but they're all surprisingly tractable with other market mechanisms.

There's a whole literature on this topic in economics under mechanism design. They've been a longstanding research interest of mine, I consider it almost like the land value tax of legal enforcement by this point.

bluefirebrand · 1h ago
I really don't understand why anyone would want this

Do you really want to live in a society where we're monitored for even the slightest infractions at all times and automatically punished regardless of any circumstances that might explain the behavior?

hiAndrewQuinn · 7m ago
In Crime and Punishment: An Economic Approach, Nobel Prize-winning economist Gary Becker showed crime can be discouraged if the expected punishment outweighs the reward. Expected punishment has not one, but two important factors: How big the punishment is, and how likely the punishment is to actually be levied.

Punishment likelihood depends on how likely the crime is to be detected in the first place. Older societies such as medieval Europe or Qing dynasty era China used the death penalty for so many seemingly minor things, and this formula was a big part of why. State authorities at that period of human history had a very low chance of actually detecting something like forgery. So in order to deter criminals they had to ratchet up just how big the potential punishment actually was if you did get caught.

Conversely, as our societies have improved their ability to detect crimes, our stomach for policies like “Forgery is punishable by death” has rightfully taken a nosedive. So, yes, the trend I've seen across the centuries suggests to me I might well prefer to live in a society where the detection rate is higher than it currently is. There's no reason to suspect we've hit upon the optimal point for human flourishing where we are now.

gorbachev · 58m ago
New York City doesn't do this for "even the slightest infractions at all times".

The idling regulations are based on real harm, and the reporting requirements include things like recording video to prove that the car you're reporting didn't start idling in the last 5 seconds, but has, in fact, been doing that for 3 minutes or longer, or 1 minute or longer adjacent to a school.

More info here: https://www.nyc.gov/site/dep/environment/idling-citizens-air...

You have to actually submit a 3:01 (or 1:01) minute video as part of the report for that to be actionable.

And, yes, I would really, really want to live in a society where unnecessary idling is not allowed. And if I was living next to a street corner where that happens regularly, I would be on that street corner recording videos any time I'd have free time, and more, if I had babies, who are especially vulnerable to air pollution, living with me.

collingreen · 1h ago
I get your take and agree with the sentiment BUT I don't think this somehow requires "automatic punishment". Also, if the laws are there then I tend to think they should be enforced. Maybe this kind of thing will empower places to drop some of the laws most folks agree are "slightest infractions".
bluescrn · 1h ago
Milking motorists is very profitable. Stopping more problematic crime, not so much.

So we end up with anarcho-tyranny, where 'real' crime is policed poorly, if at all - but loads of resources and tech are deployed aggressively policing+punishing mostly-law-abiding people for the most minor of infractions.

mjmsmith · 1h ago
This has nothing to do with "milking motorists", whatever that means. (The phrase generally seems to be used by people who are angry that they can't speed and run red lights with impunity).
gametorch · 48m ago
> This has nothing to do with "milking motorists"

Forcing motorists to pay for minor infractions is the entire point of the app.

bluescrn · 43m ago
So when actual criminals leave their stolen getaway car idling as they go and loot a store, the owner of the stolen car now gets an extra fully-automated fine with likely no way to appeal it, and the real criminals get away free.

I feel it's Orwellian, or Stalin-esq to have us being paid off to snitch on each other.

Certainly, if you have evidence of murder or something, please do report it.

But for an idling vehicle?

Note that these laws are only targeting idling while parked, rather than during normal use, such as at a traffic light. This is called "true-idling" or "long-duration" idling.

Has anybody considered how much CO2 or other greenhouse gases are actually released by "true-idling" or "long-duration" idling vehicles, either individually or in aggregate? I spent a few minutes researching it with an LLM and couldn't come up with much. Most of the information and numbers I got were for ALL idling, including during normal driving like at a traffic light. My guess based on that is that it (true idling) is a trivially small amount of CO2 compared to the overall.

But it's plenty to earn yourself a nice payoff at the expense of your hard working delivery driver!

paulgb · 27m ago
I think the intent is less about the CO2 emissions as about the air quality that people have to breathe (hence a stricter standard in some locations).

I don’t know about measurable effects but I hate when I pass a long-idling truck and can taste it in the air.

gametorch · 12m ago
> I hate when I pass a long-idling truck and can taste it in the air.

And I hate living in a surveillance state.

toast0 · 21m ago
> I feel it's Orwellian, or Stalin-esq to have us being paid off to snitch on each other.

Sure, but it's a different kind of dystopia to have commercial vehicles idling and fouling the air outside of normal driving. As described where you have to capture 3 minutes of idling (1 minute near schools) and assuming most people take a while to notice, rather than starting the timer immediately when the vehicle stops, it seems like a reasonable way to enhance compliance.

Idling while parked may not be a large contribution to total emissions, but it's harder to justify than idling in normal operation, and easier to enforce against, so there you go. Sometimes refrigerated transport more or less needs to idle to keep the contents at temperature, not sure if there's exceptions for that or if they just need to retrofit with more insulation or batteries to run the compressor or etc in order to comply.

Idling at lights probably gets reduced by auto start/stop in new vehicles as well as congestion charges reducing traffic and probably dwell time at lights. Auto start/stop isn't a universally loved thing; it makes some cars really frustrating to use, but when done well, it seems like a reasonable tradeoff to reduce unneccesary emissions.

Genuinely curious, why aren't people allowed to say this is dystopian without getting flagged? What rule, specifically, does that violate?

I think this is dystopian. Paying people to rat out their fellow citizens. Nightmarish.

What if this idea was applied to the laws ICE is trying to enforce? Would you think that's dystopian?

rafram · 44m ago
This program specifically fines businesses with fleets of commercial vehicles (delivery trucks, buses, et cetera) for illegal idling, and escalates the fines for repeat offenders. You can't report random individuals, nor would I really want to build an app for that. The point is to get businesses to stop polluting.
gametorch · 42m ago
Okay, that makes it a little less dystopian.

But you make money off people snitching.

And you're setting the stage for something far worse, imo.

paulgb · 33m ago
I see where you’re coming from, but the alternatives are either that the law isn’t enforced, or the state ramps up its own surveillance, which is more dystopian to me.

I see this as in the same vein as SEC whistleblower awards, which I’ve never heard described as dystopian. Businesses just don’t have the same expectation of privacy that individuals do.

gametorch · 30m ago
I mean, the law not being enforced is wayyyyyyyyy less dystopian than this app and the numerous other ones like it that are bound to spring up.

Maybe a bunch of people just don't agree with your position. (If they're idling and I report them, I'm a snitch. If I don't, I get to breathe the pollution. Why is snitching worse than poisoning people in your city? Why should the snitch be the bad guy in that situation, rather than the polluter?)
gametorch · 20m ago
False dichotomy. Both the snitch and the polluter are bad guys.

If you want an example of widespread application of this idea in a society, look at China. I rest my case.

whycome · 1h ago
That’s the problem. Major polluters have convinced people it’s the small scale production to attack rather than the giant industrial polluters. We also allow incredibly inefficient engines that produce lots of pollution.

How about a pollution credit trading program then? If my efficient car produces way less pollution than your gas-guzzling truck, I should get the room to idle until I reach our agreed max.

A technological snitch program is a weird and messed up outcome when we ignore the base problems.

But, cool technical achievement. I’m scared that a similar parking snitch program is all too easy as well. Car parked 3.5 hours in a 3hr max neighbourhood? Get them fined and get a sweet bounty! Thanks I hate it.

New York City has already implemented a congestion surcharge in Manhattan to destroy demand for using personal vehicles, and has a robust public transit system. The only step left would be mandating EVs, and outlawing combustion.

Right now we are in the “laws are seldom actually enforced” regime.

It seems pretty clear that laws will be enforced more in future, the obvious response is to go prune the laws to get rid of the ones that we actually aren’t OK with being enforced.

bluescrn · 1h ago
Laws will be enforced if it's safe and profitable to do so, especially if the process can be fully automated.

Meanwhile, industrial-scale shoplifting, hard drugs, sex crimes, riots. No automated enforcement possible there, let alone profitable automated enforcement.

theptip · 49m ago
I feel things like shoplifting should actually be automatable, it’s a question of ROI currently.

One idea I play with is “police 2.0” where you can dispatch a small fast drone to a crime scene, and follow the perp from a safe distance. A lot of crimes could be solved this way (eg car chases, illegal dirt bike gangs, petty robbery etc).

I really don’t want pervasive surveillance, but perhaps there is a middle ground where response times are fast enough that you can be purely reactive to a 911 call/app.

Feels quite slippery-slope though. I think we should expect increased debate on the social contract as these new systems become more capable and the “enforcement gap” becomes larger.

I don't care what you guys do in your wondrous city. But man, I remember freezing my ass off in a truck because of this, stuck in NYC, waiting, waiting, nowhere to go. You might argue that I chose to work for a company that didn't install an APU. All I know is that it was difficult, and layering didn't help.

I never went back, and won't ever go back to NY, for any purpose. Many drivers feel the same and refuse to go. If ever NY became severed from supply lines, I'd always remember my time there.

Guess it's time to gray out now. So long.

I think facial recognition and even tracking people have lot of opportunities in the world. Just imagine if we could equip each crossing with cameras that track violators of rules like jaywalking. And if they mask up they are tracked through the city to their homes.

We could even bring shame back. You walk against red light and your face gets plastered around billboards as named criminal.

Next step would be to introduce some type of social credit like credit score. Too many minor infractions and your rights get removed. Eventually electric locks in your home would refuse to open until you do enough positive unpaid voluntary work online.

I'm unsure if you were obliquely referring to this, or if you were intending to suggest a fictional idea. But what you described is already a thing that's happening in mainland China,

> "In the southern city of Shenzhen, Chinese authorities have launched a new surveillance system loaded with facial recognition, artificial intelligence, and a big database to crack down on jaywalking as well as other crimes."

> "As a result, photographs of pedestrians caught in the act, along with their names and social identification numbers, are now instantly displayed on LED screens installed at Shenzhen road junctions."
