Also, the notion that there is some universal speed limit that makes driving safe on a particular road is silly.
Two scenarios with speed limit of x: 1) sunny day, brand new porsche, new tyres. I'm driving at a sped of x+5 2) windy, snowy day, nissan sunny from the 80s with almost worn out tyres. I'm driving at x-5
Pick the safer one. I doubt anyone would think option 2 is safer, yet 1 is illegal and 2 is perfectly fine.
In cities and suburbs where kids can run into the street in unexpected places - more thought is needed what is the best solution.
I've actually gotten a speeding ticket because I was going 35km/h in a "construction" zone with a temporary 30km/h limit on a freaking Sunday with nobody around. That is also clearly ridiculous.
Has this also resulted in traffic bunching up? That is, long lines of vehicles tailgating each other?
They recently installed a new radar at a local highway, right at the beginning of a speed limit.
Everyone sticks to the speed limit now.
A different section of the highway has "section control". (Cameras at the beginning and end of a section that record license plates and determine average speed). Nobody speeds there either.
With todays technology it is trivial to enforce speed limits everywhere, and people really do stick to the speed limit if they know that there are consequences.
