>In reality, macro-scale rerouting around obstacles that the self-driving system does not know how to overcome is not a particular challenge, GPS systems do this easily. The definition doesn't say it has to take the most efficient route. ;) Oh, that's going to go over really well. Say you're drunk, and want to go home in your self-driving car. However, there's a blind left turn that your car knows it can't safely navigate, so it happily routes you a 15-minute drive through back roads for a trip that should take 5. People are going to love that. (I've heard that UPS does route planning with a system that discourages left turns, even sometimes doing three rights to avoid some dangerous lefts.)
