Not in terms of throughput though. Buses and trains still have em beat.

In rural places, not only are there no buses or trains, there's hardly any taxis. Maybe during the day if you wait an hour or two, but you're not getting home at night without your own car.

A couple robot taxis roaming around every rural country in the US comprehensively solves this problem.

Agree. Though I imagine the cost to run robot taxis in low density areas would be much higher than in high density areas, as there'd be a higher distance between rides, and so more wasted time and gas. I suspect that would slow adoption.

Also if we dream big here, I wonder how robot buses would work in low density areas, maybe with dynamic routes and pricing?

This is true for intersection throughput, but I bet full travel throughput (walking to the bus, waiting for the bus/train, walking to your destination) is the same or better with Waymo.
