My two moving vehicle "accidents" were down to my failure as an inexperienced young driver to tell the difference between a speeding car and one travelling at normal speed at night and an inability to look forward, backwards and sideways at the same time. An autonomous car would hopefully suffer neither of those problems.
I've had three other incidents that damaged a car; the first two the car was parked and I was in bed asleep and the third involved a shotgun owner not paying attention to where he was shooting. Universal AI would fix the first two, the last one is probably beyond current technology.
