I actually agree with everything here, but on the other hand the decision of whether and how to actually build the massive amounts of non-car infrastructure we need to have transport be efficient and accessible without private cars of any kind, is in a whole different place. At least in the US, it's pretty clear that in most areas there is very limited political will, even in the grass roots, for things like "build good high-speed trains" and "dig new billion dollar subways" etc. So I think pragmatically speaking things like robotaxis are going to be the "solutions" that we'll actually get.

(And yes, I agree that that's dumb since the same politicians and voters have no problem indefinitely subsidizing and expanding the massively money-losing infrastructure called Roads at taxpayer expense!)
