I would think for one with a self-driver, the inclination would be to have it park itself for free on a nice side street nearby, rather than drive back home - maybe take itself for a car wash or servicing too.
I also foresee them cooperatively owned and operated as a door-to-door carpool vehicle available for doing run-arounds during work hours, or even earning ride sharing side income. This could eliminate the need for and expense of the second family car.
