That's more or less where the major auto manufacturers are all headed in the near- to mid-term. I realize a lot of people don't get excited by something that isn't on-demand door-to-door transportation. But it seems fairly obvious that full highway self-driving, especially limited access highway driving, is a much easier problem that is mostly solved today. It could end up being decades ahead of general-purpose everywhere/when autonomy. The only real question in my mind is when you transition from systems that are at least nominally assistive to hands off the wheel under certain conditions.
