this is also something that's oddly absent from the self-driving debates. Mass deployment of the same models or apis in automated systems is very brittle because it means errors are highly correlated. it's like a form of central planning.

individual drivers or individual taxi firms in a market due to their decentralization are much more robust to any kind of individual failure.

People often ask "is the car smarter than the driver?" but the correct question would be if the car, or system is more diverse than the aggregate knowledge of all the participants.

Yes. Additionally, this is a commonly cited win of cars in cars v. public transport. You can take your car anywhere in the zombie apocalypse*, whereas any system that requires central planning (trains) are more likely to break.

Making cars (human or machine driven) depend on a centralized service basically takes away that advantage.

* assuming you have enough fuel/battery

Typically in apocalyptic settings the roads are quickly clogged with abandoned vehicles.
