Yeah, others have had some good counterpoints on this too. Maybe another argument with the same point, is that you can't be ready to drive at any moment if you're gawking at the scenery, etc.? (Or is the system actually going to be able to drive certain routes with a "driver" who can allow themselves to not think about driving at all?)
It seems like at some point there would be a qualitative change in the mental processes, where you're effectively not alert to driving, even if you think "I'm only looking away every few minutes." At least if you have been driving for years, where "driving" = "re-evaluating road and vehicle conditions every 3-5 seconds and reacting appropriately." Maybe it should be thought of as learning a new skill, passive driving.
