This makes me wonder why this shouldn't become the default mode of public transport — i.e., subsidized by the local govt in the same way as busses/trolleys. It seems they could actually replace the busses and provide better service with a sufficient inventory of cars. Could even provide Waymo-style vans on regular++ routes, with the "++" being ability to divert to nearby residences, especially for the mobility-impaired.
Why? Why Not?
