The flow of traffic is always the safest speed. NHTSA and German authorites have papers on this.
It is possible to physically slow cars down with narrower roads, speed bumps, one lane chicanes, etc. It works. Very well.
Four lane split highway with a 30mph sign next to a police station? That's a speed trap and everyone knows it.
You must have dumb drag racers where you live but then again, most drag racers are dumb to begin with. Our drag racers remember where these speed bumps are and just adjust to them. You literally hear these morons slow down and rev up again in the middle of the night.
Frankly, it's the noise that's the biggest issue with me. I wouldn't care that much if they raced quietly. I'd prefer extremely heavy fines, loss of license and even prison for anyone causing excessive noise pollution in residential neighborhoods. Especially at night.
Drag racing is unfortunately impossible to stop with force because we lack the political will to do anything like that in California. Narrowing streets and making it difficult to race or do donuts is more politically realistic
Used to find back corners of industrial parks to have fun. Cops were cool with it. More than a few were there off duty doing the same.
I dealt with tech inspections and people would try to go on the track with worn out brakes and suspension all the time. Which is dumb but. So are people.
Even getting to that point means you've gone through the local amateur licence process, shown up to training days, etc.
You have to prove to a bunch of gatekeeping boomers you deserve to race.
If you want to do wheel to wheel racing with other drivers, then there's a license requirement involving a couple days of training with a four digit price tag.
Maybe we have different thresholds for what counts as "bureaucratic shit", but there seem to be some good options to drive fast under controlled conditions and compare your results to others. The most exciting and dangerous versions of it have some gatekeeping and I imagine most of the participants prefer it that way.
What about emergencies? If cops, firefighters or ambulances need to get somewhere quick?
> I've seen people drag racing on residential streets because they are 50 feet wide with clear zones on each side.
People drag race in residential areas because they feel they can do so with impunity. If politicians decided to take on this problem head on, we can solve it easily. Make drag racing and noise pollution with cars/motorcycles/etc in residential areas a serious crime ( that includes prison time ). Problem solved.
