Earlier quoted context omitted.
Nobody is going to sit and wait for a robo uber in the suburbs for ten minutes to go to the grocery store ten miles down the road. This is the main problem, America has suburbanised itself to hell and no amount of robo taxis will create the world you are suggesting. And elsewhere in the world there’s no need because most places have adequate public transit which solves the problem way more efficiently than robo taxis…
Why would you wait for 10 minutes? Robo taxis would be driving all around to be optimally available to the market.
It ends up being another form of public transport — perhaps one with no predictable timetable, or perhaps timetables are themselves a useful Schelling point, I wouldn't want to guess.
But as fixed bus routes make it possible to plan things like bus shelters, I think I'd prefer a bus over the logical progression of self-driving "taxis" that constantly move rather than finding parking spots.
