Self driving will need to account for any possible edge case on the road to be perfect. To be better than humans? I don't think so. When a human driver kills someone due to lawbreaking from a third party throwing an edge case that they couldn't handle, we say the driver was "not at fault". We even abuse it for "edge cases" that the driver could obviously handle if not for normal human distraction. Why hold the robot to such a higher standard?
