Uber has drivers. There's probably some reason to customize car design for taxis, I'm not sure, but that's a modest difference relative to no driver and the greater expected scale of supplanting most human driving in time.

Whether Uber has drivers or had automated drivers doesn't really matter. I think they show that there isn't much business in point-to-point "automated" car rides.
