I have also been surprised that streets/highways aren't being whitelisted, and I wouldn't be surprised if we start to see that as autonomous vehicles become more mainstream. I can imagine a system that does not allow autonomous driving on roads that have not been surveyed in, say, the last 24 hours by either another sensor equipped vehicle or perhaps a drone. When planning a route, the autonomous driver would either plan around a road that had not been surveyed within that time frame or plan a place to stop and ask the driver to take over well ahead of time.
