What other vehicle will change lanes by itself, and take on/off ramps through interchanges to take you where your navigation is routed, without you touching a single thing?
OK, sure. You have to touch the wheel or it turns off.
What I mean is, you are not providing input to the wheel, or pedals, or turn signal or driving the car in any way. You're just letting it know you have not fallen asleep.
None, because every other manufacturer is more concerned about not killing people than they are about releasing beta features for cars. The most surprising thing to me about autopilot is that Tesla hasn't been sued into oblivion for it.
