If only speed cameras worked to lower the speed anyone travels at… Realistically, people are going to drive the speed that feels safe for that road, and a speed camera is just going to disproportionately punish people without the money to pay the fines.
Make roads that are designed for the speed you want people to drive at, not wide open expanses that give no actual reason to slow down.
If only speed cameras worked to lower the speed anyone travels at
They do. They objectively do. How are there so many people all over this thread just confidently asserting complete, disprovable bullshit, and why is it getting upvoted? From the Cochrane systematic review:
Thirty five studies met the inclusion criteria. Compared with controls, the relative reduction in average speed ranged from 1% to 15% and the reduction in proportion of vehicles speeding ranged from 14% to 65%. In the vicinity of camera sites, the pre/post reductions ranged from 8% to 49% for all crashes and 11% to 44% for fatal and serious injury crashes. Compared with controls, the relative improvement in pre/post injury crash proportions ranged from 8% to 50%.
Authors’ conclusions: Despite the methodological limitations and the variability in degree of signal to noise effect, the consistency of reported reductions in speed and crash outcomes across all studies show that speed cameras are a worthwhile intervention for reducing the number of road traffic injuries and deaths. However, whilst the the evidence base clearly demonstrates a positive direction in the effect, an overall magnitude of this effect is currently not deducible due to heterogeneity and lack of methodological rigour. More studies of a scientifically rigorous and homogenous nature are necessary, to provide the answer to the magnitude of effect.
I would love to see a more recent study. Safety tends to be a weird subject, particularly the treadmill of introducing safety features, which means more drivers drive unsafely because safety features give an appearance of safety.
Overall, I still stand by what I said outside of maybe the very first sentence. Even if they DO slow traffic, there are vastly better ways that don’t have a disproportionate impact.
My city started putting in speed cushions at roads that were constantly over-traveled. Neighborhoods that would see increased traffic during rush hour, for instance. They’re aggressive, you have to go BELOW the speed limit to safely drive the route. Those roads see SIGNIFICANTLY less traffic, and the traffic that is there is slower.
Fines just don’t work to deter your average driver, or at least not as much as physics does.
Oh yeah, just to be clear, I’m a massive fan of urbanist channels like NJB and absolutely stan the shit out of traffic calming measures. Give me more trees on the sides of the road to make it feel narrower. Give me speed humps. Give me medians. Give me sidewalk extensions. Give me roundabouts. Inject that shit into my veins. I see speed cameras as just one tool in an arsenal to create safer driving conditions, and mercifully, it seems like the US is starting to warm up to those.
I’m pretty sure we’re 100% on the same page here as far as traffic calming measures go, and I think we’d both agree too that if there are fines, they need to be adjusted to account for income. (Here’s an upvote by the way to counteract that downvote; this is one of like two reasonable takes I’ve seen in this thread against speed cameras.)
Interesting. Mostly what I see is people slam on their brakes near the camera, then take off again after it.
My theory: There’s so little enforcement of the traffic laws here, they might as well not exist. You’re almost certain NOT to get caught, so people will do whatever they want and will practically always get away with it. I don’t really want to argue for more cops, but when I’ve driven in areas with more traffic enforcement and visible police presence, people tend to drive much more sedately.
I drive and ride bicycle, and I would LOVE if the cops came riding with me some time. I see some of them doing the 100 mile ride for charity in our county, so I know they have people on the force who ride fairly seriously. Join one of our regular group rides wearing cycling clothes (not police gear), get another cop stationed ahead in a car or motorcycle…and start pulling over some people who buzz us or roll coal. Word would get out very quickly.
For me personally, I think more cops isn’t the ideal solution. Instead, I think traffic calming measures should be introduced to make drivers feel less safe if they choose to speed.
Better enforcement is 100% necessary, and I think speed cams can be a good way to prevent dangerous driving through the threat of enforcement. That said, I also think in terms of cost efficiency that direct preventative measures such as speed cushions, bollards, trees, medians, sidewalk extensions, lane narrowing, roundabouts, etc. will be more cost-effective to some point than and should be used in conjunction with speed cams.
That’s not true. They are not traveling at safe speeds. Crashes over 70 mph have a sharply increased risk of fatality. Yet people routinely choose to go faster. They even choose to bully people who won’t go faster on 65 mph roads.
Rules are put in place for a reason, but people treat speeding like an oopsie daisy because that’s how the law treats it. We need more speed enforcement and tougher penalties. Not less. This is an area where people’s feelings are very very wrong.

And often even this is too generous. Most drivers I’ve seen in the US treat speeding like a calculated risk that they feel out over time. They will with an unambiguous understanding of what the speed limit is choose to not just exceed it, but to actively target a speed that’s (usually 5 mph or 8 kph) over it.
That’s because eons ago a judge determined the error rate for speedometers and radar guns was around 10 mph and we couldn’t punish people for something they don’t realize they’re doing.
Completely rushing past the fact that not realizing your speed is itself a giant red flag.
And that has absolutely contributed to the sense of entitlement to speed.
I don’t disagree with anything you said. Slowing down is a good thing.
The problem I have with this approach is that speed limits either do nothing, or do marginal work compared to designing roads that aren’t able to be driven at excessive speeds. Narrower lanes, chicanes, medians, speed bumps or cushions - all VASTLY more effective at actually slowing traffic than a camera or cop saying “hey! Slow down or pay the toll!”
We can’t do that for most of the roads. We really do just need more traffic cops, tougher penalties, and more cameras. Part of the reason people speed is because getting caught is like getting struck by lightning. I’ve seen people do 80 right by a cop and the cop doesn’t stop them. The level of enforcement is not commensurate with the safety risk.
What the hell this is new, so road safety was created to hinder the poor? Just drive below the speed limit and stop making stupid excuses
I didn’t say it was created to hinder the poor.
I said fines DISPROPORTIONATELY PUNISH THE POOR.
If you have $1000, a $200 fine is 20% of your money.
If you have $2,000,000 a fine of $200 is . 0001% of your money, basically nothing.
This means that, relative to their money, a poorer person hurts more from the same fine. This is a BAD IDEA for enforcing rules everyone is supposed to follow. Essentially, we’re encouraging people to drive slow, unless they can pay the toll for speeding.
There are ways to mitigate this - sliding scale fines, for instance. I personally don’t like fines as punishments in general, though. I’d rather use neutral traffic calming features, that always invariably impact people who use the route the same, and make it a criminal offense to drive recklessly, akin to drunk driving.
Finland have it sorted:
https://www.theguardian.com/world/2023/jun/06/finnish-businessman-hit-with-121000-speeding-fine
“A multimillionaire businessman has been hit with one of the world’s highest speeding fines – €121,000 (£104,000) – for driving 30km/h (18.6mph) over the limit in Finland, where tickets are calculated as a percentage of the offender’s income.”
I don’t disagree it’s disproportionate. But you know how rich and poor can avoid fines? Just fucking respect the limits
People should follow the law because it benefits everyone not because they want to avoid a fine
Traffic jams are caused by speedcameras because those who are speeding hit the fucking break paddle as hard as i want to slap you for saying bullshit
