If we make those cars self-driving, they might be seen by consumers as the same as an automated taxi, even if they own the deeds to those taxis. If that happens, we might want something else out of our cars: we don't care what a taxi looks like, after all, so maybe a point-a-to-point-b machine would be enough. Ownership in general gets "put into question" with self-driving cars, he says: what does a parking space mean when the car parks itself?
