Why should speeding ticket funds not go to local governments? Noise may be damaging, but to a much lower degree than a violent death by car crash which speed limits reduce.
Just want to incentivize switching from radar gun to sound gun. Local departments are who principally enforce this, and taking away a reliable speeding revenue source should hunger their budgets up a bit for the noise enforcement. I'm sure laser speed acquisition could be added.
Because it causes really bad incentives. Sometimes including making roads more dangerous with speed changes!
Roads are never less safe by reducing the speed, except in the case that the road design didn't also change to accompany the reduction. If you slow down a 60mph road to 20mph you need to signal with the design, that it's not safe to go fast here. Reduce the lanes, width, remove the demarking areas etc.
I don't mean the whole road, I mean segments. The speed changes while driving on it, not compared to what it was months or years ago. And then, yes, not using the design to signal the speed changes. If they're even in charge of that.
