I suspect fully automated self-driving cars are a good ways off yet.
Partly I suspect this because other transportation systems that are much simpler to automate, and indeed that we've had the technology to automate for many years, are still human controlled. Trains, for instance, with very few exceptions have engineers to control them. Ships have captains. Airplanes have pilots--and automating flight (at least most aspects of it) is quite a bit simpler than automating driving because the environment is somewhat more controlled in the sense of having fewer and less frequent unexpected things intruding into it and having far greater separation between vehicles. Having the third dimension available to spread out traffic really helps there.
A self-driving motorhome would be really neat, though. Fill up with gas in the evening, set the destination for your next stop, and then eat dinner, take a shower, and sleep for the night while it whisks you there effortlessly. Or, perhaps more practically, actually enjoy the scenery rather than being vaguely aware of it out of the corner of your eye....
