> You have no basis for saying it will be relatively insignificant.

People can already make a few bucks by letting strangers use their car on services like Turo, and it is relatively insignificant. That self driving capabilities will change that is a baseless assumption.

No, it's a realistic assumption because currently there's enormous friction in both getting the car to the person who needs it, as well as installing systems for electronic access.

Self-driving capabilities will get rid of the friction, and so the market will take off.

If we followed your logic, then AirBNB would never have happened because short-term rentals of people's homes and rooms were "relatively insignificant" in the 1990's. But of course it did, because AirBNB removed friction and provided a platform for reputation management and dispute resolution.

You don't want to rent out your personal car, I get that. But tons of other people prefer to make money instead.
