Why does everyone drive 10-15 miles above the speed limit?
-
Why don’t we raise the speed limit if that’s how fast everyone wants to go?
-
Why is traffic enforcement given to very expensive and ineffective police instead of cheaper and more automated traffic cameras?
-
Why do we refuse to ever use ANY traffic calming measures? Yes, than you flashing digital sign for telling me I’m going 10 miles above the limit on this incredibly wide and straight and flat road with high curbs and perfect visibility.
It’s a serious confusion I have about how society is supposed to operate because it seems like a complete and total breakdown of logic and sense.
And, yes, I know there’s some thing people did long ago to set the speed limit at some percentile of what people were already traveling at, but that’s obviously a stupid way to do it and we did it anyway. So why?


Genuine answers from what I’ve heard regarding laws at least in CA:
There is a precedent that you should be going with the flow of traffic, which is technically safer than going the speed limit when everyone else is faster-- but mostly only on freeways; I rarely the flow going that fast on streets, so the rule doesn’t apply to that one jackass going 60 in a 40 zone. And yes, you’ll just get to the red faster (good cities time popular traffic lights to the speed limit so it’s even stupider to speed).
I’m pretty sure they also set the limit to what older vehicles can pull off safely (assuming you don’t tailgate, anyway). They have upped the limit in some areas, however, which I found upsetting. Like, 70mph up from 55mph over a few decades, which feels fast.
Traffic cameras are used, but there’s an interesting issue on legality. If you don’t acknowledge them, they can’t actually say you got the ticket (they come in the mail). I forget the details, but something about seeing your accuser? LA itself more or less decriminalized them, but your mileage may vary based on local government.
Places do, in the form of speed bumps, stop signs and curved roads. Not using those is probably more a mix of old roads and poverty-- new suburbs use windy, wide roads. Wealthy neighborhoods install speed bumps and add tons of stop signs. I don’t see it in my neighborhood because “it’ll hurt business” which feels like code for “you don’t matter enough for safety,” hence I think it’s a wealth inequality issue like most things in this country.
Anyway, that’s the best of my knowledge as a CA resident. Honestly, the bigger danger to me are people who tailgate, road rage, drive on sidewalks, and do stupid things to get to an offramp. That last one? Just last Wednesday I saw a guy, car totaled, who tried to hit an offramp they missed by sharp turning into it, going up a 55 degree slope, and getting t-boned by another guy going up the normal way.
Idiots, I swear…
