The thing is that everything you mention here is related to each other or is a consequence of each other. Car oriented urban planning leads to an explosion of distances which leads to an explosion of infrastructure and mobility costs and makes public transit unattractive or even unfeasible. All of that was kept together by dirt cheap fuel.

One can change that of course. The US was bulldozed for the car before and it can be transfirmed back to be transit oriented again. However even with the political will and the money, this will take decaded. Fuel prices can explode in weeks, for good.

That is a hole the US is in that it has dug itself. There is no easy way out.
