Why not figure out what distance it takes to get going say 30MPH and install speed bumps at those intervals? They hurt if you go over them to fast so its a disincentive to do so.
Tons of European cities already set-up speed-limit to 30 km/h. It’s not just large cities, I’ve seen villaged limited at 30 too.
it’s basically less nuisance for the residentsSing it with me, folks…
You 👏 can’t 👏 reduce 👏 the 👏 speed 👏 limit 👏 without 👏 also 👏 changing 👏 the 👏 street 👏 geometry! IT DOESN’T FUCKING WORK!
People don’t give a shit about the what the speed limit sign says; they drive at the maximum speed at which they feel safe and comfortable based on the lane width, curve sharpness, etc. If you want to slow people down, you HAVE TO physically change the road – narrow it, add chicanes, etc. – to make it “feel” less safe. It’s not fucking optional!

Given that we know going over the speed limit raises your collision rate, meaning setting the speed limit so low every driver will go over it is genuinely dangerous, do we have any studies supporting the claim that reducing the speed limit reduces the collision rate overall? I couldn’t find one, but it’s a surprisingly challenging search - I easily found studies confirming that collision lethality scales with speed, but that’s not my question.
Purely anecdotally, the vast majority of my collisions have been at very low speeds - in parking lots.
