A 1.5 mile, closed course, controlled environment, is a long, long way from the chaos that is the LA freeway system ... and an even longer way from avoiding thunderstorms, with tops at 60,000, won a MEL flight and landing to mins (although with unmaned, the point would be no mins) and doing that over and over on a consistent basis.
Then you have the "fear factor." The general public just isn't going to accpet it. Now, a few generations down the road when there are none of us left who remember the world without computers and it may be a different story.
