Well, one thing is that many of us rarely take taxis. (Aside from reserved private cars to the airport now and then.) I'm unconvinced that self-driving changes the equation enough for most of us. I do have a trip coming up that 50% cheaper Uber might lead me to not rent a car but that's rare.

Outside the US the situation is quite different. But I don't see Waymo testing outside the US, not even trying, so there.

Car ownership is pretty high in a lot of places. It's still pretty much central urban--lower ownership, harder to re-find a parking spot--vs. everywhere else. Taxis may be more common in some places but there are still a lot of privately owned cars and taking taxis or having drivers is really not the norm in most places.

Nevertheless the comment I was answering to was about renting a car instead of taking a cab or the public transport.
