You probably don't need to go crazy with stuff like that. Speed cameras seem like effective deterrents. When I drove around the UK, speed cameras were everywhere and people generally all did the speed limit or below.
The USA has a weird cultural obsession with being able to break certain laws. We need to rethink that. If we aren't enforcing laws, then we need to get rid of them, if we don't want to get rid of them, then we need to enforce them.
