https://www.eastoftheweb.com/short-stories/UBooks/TheyMade.s... - love this short story and its take on that question.

A classic, and regularly shared here on HN :)

I really like this version of it personally: https://www.youtube.com/watch?v=T6JFTmQCFHg


What I like about the automation of rules is that it takes away targeted enforcement and the opportunity for leniency to be offered only to certain groups.

The UK model for speed cameras is that they can (generally) only be placed in areas that have shown to have a higher than average number of accidents on the stretch of road, caused by speeding. So at least (in theory) they are focused on reducing accidents and not raising money.


We have a bunch of red light cameras which actually cause more accidents than they prevent. Perhaps t-bones are more dangerous than read-ends, but accident prevention it isn't.

Those who would give up essential liberty to purchase a little temporary safety, deserve neither liberty nor safety.


Do you have any data on that?

It seems pretty messed up to suggest that we shouldn’t enforce people not blowing through red lights because then they’ll slam on their brakes and cause rear end accidents instead.


Not GP, but I've seen multiple credible news stories on this.

The problem isn't the red-light camera itself, it is that whoever installs/manages them also reduces the time of the yellow-light warning, so the red light comes on significantly sooner. The normal yellow light timing is a properly studied and engineered interval based on traffic and speed to give drivers sufficient warning to see, decide, and go or slow-stop in a safe and predictable fashion.

When the red-light-camera installers/managers decide to cut that time to increase infractions and increase revenue, they create situations where drivers think they are going to make it to the intersection in good time, but are surprised by the sooner-changing red light, so emergency-brake before the line. This causes accidents, including accidents where the car is pushed into the intersection and causes a rear-end then T-bone.

This invalid yellow-red light timing was revealed in some lawsuits about it.

I think the right solution is to maintain properly engineered timing, install cameras that also trigger a full video from multiple angles, and manually evaluate each positive and ticket only the egregious ones and have records of the violators who caused accidents.

But since the easy money is evidently too much of a temptation to fck with people, ban them all.


If we have the ability to ban things in this world, why don’t we ban the actual negative thing, not the potentially helpful thing that’s being abused?

Human nature.

We already ban the thing that is being abused — running red lights. Yet people do it with deadly results so much we're looking for another solution.

With the cameras, the camera salespeople and the town managers just can't get away from "It increases revenue (and if we screw with the yellow-light-timing we can increase it even more!".

I'd be all over making any town manager and red-light-camera-salesperson involved in a decision to screw with the red lights personally and criminally liable for any accidents resulting from screwing with yellow-light timing, and requiring all timing before installation to be officially logged, but they'll try to find ways around that too. And then there is the whole surveillance capitalism thing — we've got the cameras, why not record all license plates, and tie them to driver license and voting records, and, and, and...

What is the least-worst thing to do?


Definitely reduce injury and deaths due to car crashes.

Red lights reduce injury and deaths due to car crashes.

Red light cameras do NOT do so, and when the companies/cities screw with the properly engineered yellow light timing to increase revenue, the cameras INCREASE crashes and injuries. It has been definitively studied multiple times, and cities have de-installed camera systems after these findings.

If cameras are installed without adjusting the yellow- light timing, the effect is not demonstrated. Thinking about it, a likely camera ticket will reduce one of three types of red-light-running, where an impatient driver slows at the red light, looks, then crosses anyway if traffic is light. That one causes few accidents — the careful drivers are already careful and either don't do it or do it with sufficient cautions accidents are extremely unlikely.

The others, where the driver fails to see the red light and blows through it, or where they are just on some criminal blast through town (evading cops, high on drugs, whatever), will not be deterred in the slightest by the cameras. The eyesight of the first will not be helped by a likely camera-automated-ticket, and the second already has far bigger legal problems coming and won't care.

So, explain the circumstances where a red light camera actually reduces accidents and injuries. I'm not even seeing a plausible measurable effect beyond revenue extraction.


There's usually a two-second delay between a light turning red and the next light turning green, just as a simple safety precaution. No driver is perfect, and red lights get run through accidentally all the time.

While running the red light is still dangerous, running it as soon as it turns red is unlikely to cause an accident. It's still ticketable, and if a cop sees it happen, they should make a stop and issue a ticket.

If you are distracted, or time the yellow light badly, and you have to make a decision on whether to lay on the horn and run the red light as soon as it changes, or slam your brakes and try to avoid running through the intersection, you're already in a position where you're going to have to commit a moving violation, and you don't need the threat of automatic monetary penalties guiding your judgement on which move to make.

There are situations where slamming the brakes creates a more serious hazard than running the red light, but the red light cameras only ticket you for running the red light. Why create an artificial preference for one hazard over the other, rather than trust the driver to drive defensively in these situations?

The cameras don't even need to go away; they just need a human in the loop to apply these tickets rationally. Maybe don't ticket the driver who barely missed yellow, but do ticket the driver who blew through the red with zero regard for the rules. Make sure these rules are understood by drivers, so that they don't fear automatic enforcement more than they do bodily harm to themselves and others, but still think twice about ignoring the rules of the road.



This seems to say the opposite, which is that the benefits of reducing right-angle crashes (getting t-boned) outweighs the increase in rear-end crashes.

How do the cameras cause the crash, and not the lights themselves? Is it that the flashes of the camera causes people to brake suddenly, or the very presence of the camera causes some people to brake at the lights and others not to?

I find it interesting, as in the UK we don't have loads of red light cameras (though we do have them) but people driving through red lights is a rarity - even when there is no-one around and at night, the vast majority of people will obey a red light.


Years ago I made a papercraft Daft Punk helmet, using standard printer paper, but glued it with super glue, and then treated it with the 'resin' from a home fibre glassing kit, to make it solid and ready for full fibre glassing (obviously not needed in this instance!)

Ooh! Were you happy with the results? If so would you be open to sharing the pattern you used?

Very happy with the results - and learnt so much making it - i.e. building my own vac forming table to make the visor.

Loads of sanding and spray painting, in-all I think it took me about 70 hours, but we wore the helmets loads for festivals and parties.

I no longer have the file sadly, but got it from a paper craft forum - where people posted them. Happy to share pics if of interest.


Wow how hard was it to make the vac forming table? Have you used it since? I'd love a link to a tutorial if you have one.

Sadly I can't find any pics of the basic table we made, but that was actually an easy thing to make once I thought it through.

I basically got a 2 sheets of MDF to the size I wanted (roughly the size of a baking tray for the oven, as I had to heat the plastic in my home oven) then drilled a hole every couple of cm in one of them, then made them into a shallow box - sealing all the places the wood connected with bathroom sealant on the inside and duct tape on the outside. I made a hole in one of the 'side' pieces that would fit my vacuum cleaner hose, and then added more duct tape to seal.

Then I made two wooden frames as big as the largest baking tray for my oven, then cut some heatable plastic to size, and clamped them in the two frames and put them in the oven.

This part had loads of trial and error - ie how long the plastic needed heating, how long to run the vacuum cleaner, how to make sure the plastic didn't end up behind the thing you were forming, how to make sure the think you were forming didn't deform while under pressure.

Email in bio if you want pics or more info.


Same reason I listen to music or podcasts in the car.

I am very lucky to live in a city/country where risks of theft from my person is low - when I lived for 20 years in London I never once felt unsafe listening to music.

The closest was two young men got very close to me on the tube, when I was playing on my brand new Hong Kong imported PSP - but I just took my headphones off. I think they were just interested as most people hadn't seem one in the flesh yet.

I can't say I know of anyone personally who suffered theft or accident caused by them listening to music on headphones.

When I cycled a lot, I had a small speaker strapped to my handlebars rather than wearing headphones, as I liked being able to hear cars around me - but when I was younger I regularly cycled in headphones, and was still able to hear enough of the road around me to not feel that I was missing anything.

Remember, we don't make drivers drive around with no music and their windows open, so that they are better able to hear cyclists...


Dogs are pretty terrible for nesting birds, especially ground nesting ones. Even on a leash they can cause birds to leave their nests.

Similar for other small animals;

Dogs are allowed though, and used to herd sheep and cattle, so ground-nesting birds don't seem to be a big concern


There is lot of investment going in to fanning those flames - just look at the way the edges of this are discussed in the Epstein files.

Here in the UK, it is amazing to follow just how much money has been pumped into the various 'right of the Conservatives' parties for the last 15 years, while it might seem like a grass roots movement, the majority of the cash has been coming from those with vast wealth inside and outside the UK.


And inversely, if you break the law, and they 'like' you - then you are freed or never even charged in the first place.

Welcome to the Authoritarian States of Sycophancy. Or ASS. As we are referred to around the world.


These look brilliant and remind me of the pictures from my Casio watch camera: https://www.casio.com/intl/watches/50th/Heritage/2000s/

I really need to dig that out, from memory the software only worked with Win98 or ME - but I guess there must be a way of getting it running elsewhere (or getting my ME laptop running).


Interesting article, but shame the images are blocked in the UK - guessing imgur?


I had no idea they blocked imgur on the UK. I'll move it to self-hosted!


Thank you! Much appreciated


Since when is that a thing? I'll presume they're boycotting the new age verification laws?


Its been a thing since September 30th 2025, and apparently its just embedded content on third party sites, and account features on imgur itself that are blocked. I think its a "we don't want to adhere to your data protection laws" instead of an age thing
