To be fair most Euorpean countries have 30 kph speed limits in most built up areas which is <20mph so it would bring us in line with them.
Sure, built up areas, fine, schools, fine, not a whole city though!
Speed does not cause accidents, it only determines the magnitude of an collision after it has occured the majority of accidents are caused by dangerous driving, because you can't quantify dangerous driving, and you can quantify speed, it's much easier to say that speed causes accidents, as that way it is easier to "solve" the problem.
The real solution is to improve driver skills and reactions.
