I don't think following the rules of the road the vast majority of the time is that hard. Yes, you will make mistakes from time to time, but any reasonable system would recognize that. And sometimes following the law is less safe, but that's extremely rare in my experience. The problem is that many drivers, if not the majority of drivers, have no problem intentionally breaking the law as it suits them (e.g., speeding, unsafe passing, etc.). I am a cyclist who rides with a helmet camera. It's amazing how much this seems to change some drivers' behavior. One moment they're rude and/or dangerous, the next they are keeping their distance and driving the speed limit. These drivers choose to drive dangerously because they think it saves time. (I'd argue the time savings are much smaller than they believe.) These people are the ones I think an automated system would catch, and I have no problem with that. (As a cyclist, I follow the law to the letter, by the way. You will not catch me running reds. In fact, I have gone through the local police's stop sign enforcement efforts twice and passed.)
