I wonder just what he means by "full autonomy" though. When he refers to "autonomous driving...for highways" that means that the car manages the steering and acceleration but the driver is alert and involved at all times, and ready to take over any time the car can't handle something. I wonder if he's referring to a similar concept that works in more situations, rather than a car that can drive with nobody in it.

Or he might just be optimistic and mean full automatic driving. Hard to tell.
