Where I live, I can get a cheap taxi, any time, to anywhere I might want to go, through an app. The only difference between that and Waymo seems to be that it is controlled by a meat sack rather than a computer. I don't see autonomous cars as all that different to what I have now.
Where I live is similar, it’s just the prices are prohibitive. Round trips just to locations within five or 10 miles of my house cost upwards of $50-$60. I would end up paying 2-3k a month for Uber/Lyft.
Owning a car is simply more economical. Now if I could buy into fractional ownership of a fleet of vehicles, that may make financial sense for me.
