He might be right, but it would require allowing cars to drive around on roads without anyone in them.
Using a shared, limited resource in that way is such a prototypical "tragedy of the commons" that I can't see any government allowing it.
Traffic will be insane if people can send their cars on errands without having to sit in the resulting traffic, or if hired cars can drive halfway across the city to pick up the next fare with no impact to the car's owner besides wear and fuel.
No amount of incremental improvements in capacity due to "better" robot drivers will make up for that.
