I know what you mean, but in the case of driverless cars I honestly don't believe that's ever going to happen, to any degree. Unless, as I said before, it happens to a generation that has never driven and really doesn't understand what all is entailed in navigating through city traffic - the complex situations, the insanity and the incompetence that you have to allow and compensate for, and the split-second decisions one has to make in order to stay alive and keep your vehicle in one piece. If cars and trucks had a top speed of, say, 15 mph, I might be comfortable with it. Maybe.
