>Maybe car ownership isn't doomed after all

I think if anything waymo, robot taxi is doomed. Self driving ever matures to private car ownership will to car share to subsidize costs will with 1-10% utilization will basically generate more demand than non car owners will ever need - there simply isn't business model for share only fleet outside of specific low vehicle density zones. And even for private car owners, the only ones who will generate some revenue are those that work offpeak hours, i.e. they can rent their cars during surge, which will make congestion worse for all existing drivers by increasing traffic (kek). Proliferation of self driving = eventually millions of beater supply cars doing rotations for basically marginal costs killing fleet economics.
