I'm looking forward at the handling of the "corner cases" related to society.<p>E.g. somebody that wants to rob you could just stand in front of your car (or put some small obstacle) knowing that the car will stop (to avoid damaging itself and/or whatever is in front of it).<p>Even in the case of simpler tech which is generally available already today some unexpected problems might arise once people become really aware that it exists on 99% of the vehicles.<p>For example, in the case of an at least partially selfish person, why should s/he wait to cross the street if s/he knows that the car that is nearing has an anti-collision/auto-break system? I admit that I might even start doing that myself whenever I'm late for something, have to catch the bus, etc... :)<p>Might end up being a funny experience sitting in a car that has to do emergency breaking every other minute... :)
