It costs something like $10k-$12k per year to own a car in the US. That's a lot of robotaxi rides. But I can't imagine self-driven cars disappearing either, though I can imagine them being banned in city centers within a decade.
It doesn't cost anywhere close to that unless you are driving an absolutely insane amount of miles or have some ridiculous supercar where the insurance rates are insane.
I guess we were thinking of different numbers. That's including depreciation, interest and sales tax, which I would consider purchase cost, not part of the cost to own. But
By self-driven cars you mean, a human self? By context I think you do but self-driven is maybe a strange phrase to use to differentiate from self-driving.
