The need and achievability of quality time lies on a logarithmic scale which goes downward from infancy to adolescence. When a kid is eight or ten years old, they want the bus ride and you want the train ride. Why go out of your way when you can both arrive at home at the same time refreshed? Driving is good for no one. Either through services or robots we should try to eliminate all driving that is not for enjoyment. Daily driving is common, mundane and does nothing to increase quality of life for those that have to do it. Riding is great. Driving is a chore.
