You already basically have them. The pilot mostly just gets involved in emergencies at this point. I'd assume we may see something similar with large buses soon

You already basically have them. The pilot mostly just gets involved in emergencies at this point. I'd assume we may see something similar with large buses soon... large bus with an operator paid more to keep attention than "drive", taking passengers on longish routes (Ex: LA to SF), with local metro rail handling second leg, and automated small passenger cars and/or walking closing last gap.
