> One driver driving one passenger is inherently low capacity.

Isn't capacity primarily about passenger-miles / time? Whatever vehicle size optimizes for this is probably better. During rush hours, it could definitely make sense to use big busses.

> You pay more for taxi fare because it's door to door and capacity is far scarcer than bus/train seats.

Hard to compare taxi fares to transit fares when transit fares do not fully pay for the service.

> Good luck finding a CDL holder driver who will work as a "gig" worker. Vans are cheaper than $250K buses

This is one of the strengths of these microtransit options, no specialty employees or vehicles.
