Highway self-driving is not the computational challenge that general insane-city / local street / surface street driving is. With mild convergent infrastructure (better marking policies for construction, mesh networking or broadcast messaging about road hazards and bottlenecks, etc) it will become pretty safe. And the trucking industry will push it quickly and probably within a fairly developed regulatory structure. And really that's all I want out of self-driving. Sleep or work in a car on a divided highway. That's really it. That one achievement will make short/medium trains, all intercity busses, and probably most airline flights under 400 miles not really that desirable. If my self-driving EV car gets me there even at 60 mph and I get to fill my car with crap, and I have the car when I get there, and I can load it with a family...
