surveilance or enforcement... (Score 1)

I live in the US, but uncivilized behavior on the road is a problem here too, especially in Florida where Joe Pickup Truck will side-swipe you off the road if you don't let him bully his way in front of you. My first take on this is that speed is only one of the vehicle behaviors that cause accidents and is probably simplest to detect. Weaving through traffic is probably detectable too though a bit more complex. Following too closely is a fairly easy one, again. To carry it a step farther, with enough research funding you might even detect characteristic signs of aggressive behaviors or alcohol-related unsteadiness, etc. You might add facial recognition so good that the system "knows" the name and sexual preference of every driver on the road. (I've read that this sort of thing is coming pretty soon.) So, you can likely capture the occurrence of various types of traffic events, and record individual reaction times of all vehicles involved or affected, and follow the chain of small actions by which the initial traffic event propagates into a multi-vehicle accident. The consequences of car accidents are so horrible that all of this kind of surveillance seems justifiable, but would it not be better to have a government that protects the citizenry by means of adequate enforcement and traffic lights, highways designed for safety and a social ethic of civility? I do understand something about the situation in many places in the Middle East where the governments tend not to be responsive to people's needs. (Join the club! Instead of healthcare we got the war in Iraq!) Good luck!
