From my vantage point the utility of self driving cars is in highway driving. I don't really care for auto city driving. In that context perhaps the problem is somewhat simpler if one assumes the infrastructure will be modified to help these cars. A lot could be done if each car communicated with roadside beacons and other locating systems. Some will voice concerns about privacy. I couldn't care less. Your movements are already far more traceable than they were fifty or a hundred years ago. If I could manually get on the Golden State; engage auto pilot and be alerted a couple of miles before my exit in San Jose I'd be thrilled. I wouldn't even care if the thing pinged me every 15 minutes to see if I am awake.
