Maybe the waymos could be powered by overhead wires?
You'll pay $$$ for a nonstop ride into midtown in a dedicated vehicle, or $ for a short dedicated ride to a self-driving bus you only need to wait a few minutes for, and which will drop you off on your destination block.
So yes -- self-driving buses seamlessly integrated into ride sharing are certainly going to be a major part of 21st century urban transportation. Which will save a ton of time compared to current buses.
You could even set that up on a recurring schedule, sort of like a school bus system that dynamically adjusts to everyone's locations and requirements and instantly remaps routes as passengers are added and removed to the schedule.
Far more people might able to afford a Waymo than a personal (in person) chauffeur.
