You make good points. However, I not sure that everyones whole approach to travel will not change when autonomous vehicles arrive. Are people not more likely to carpool? Carpooling is a bit onerous on the car owner, as they have to get up earlier and drive around picking up their colleagues. With autonomous, the car does that. Perhaps rush hour gets better. Perhaps the small autonomous cars drop you at the autonomous bus, and it brings in 12 people at once.
Ummm, someone must be writing their thesis on this.
Along the AP thoughts, I am not a big fan. I appreciate the technology and understand a compelling reason in reducing traffic fatalities, but the thought of most cars be driven automatically seems a little bit antiseptic and too Blade Runner/Jetson-esque. I drive a Tesla and love to drive it, not be driven by it. AP is here and is the future (being led by Tesla) and many, if not most, car manufacturers are following suit. I just hope the thrill of driving isn't replaced by being a passenger.
