The problem I have with speed enforcement as such is that speeding, in and of itself, doesn't harm anyone. Note that in my suggestions above I didn't say anything about speeding by itself; I said if you are involved in an accident and your speeding is a contributing factor, that should increase the negative consequences you suffer. That would give people an incentive to properly consider the risks of speeding; and the person who is actually driving the vehicle, and sees the road conditions and other variables as they are, is in a much better position to judge what is a safe speed than a bureaucrat writing speeding laws.
