I wouldn't be surprised if these problems proved intractable enough that the solution will be adding electronic guides to the roads themselves. Things like burying a wire that can be followed, embedding RFID devices in the pavement (along with an online database that gives their precise location and any updates on road conditions), etc. It would be conceptually similar to all the ground based systems that guide aircraft. Of course, these would be deployed only on high value roads like freeways first, and you could at least let the autodrive work on the freeways, and do the last mile yourself.
