You don't get highways and the interstate system if vehicles are not for personal use. And if you don't get those, you don't get the modern logistics system.

I guess what I don't understand is, given the current state, 1) what do you want? 2) how much will it cost? (and how will we pay for it?) and 3) what are the tradeoffs?

On a related note, it seems like a lot of the anti-car/urban planning wonks have a belief that everyone really wants to walk, ride bikes, or take mass transit everywhere, and I think they're wrong. Most people want to drive personal vehicles.

Maybe if we lived in a world where mass transit had very strictly enforced behavioral norms, more would consider it. But even then, I still think most people prefer the many conveniences afforded by personal vehicles.

I guess instead of answering your first three questions, I’ll say this:

Our world would be better without being completely dependent on cars. You can see this in a few select cities or neighborhoods that have avoided the worst of car dependency. There are still suburbs, but they’re a bit more dense and you can easily bike to a grocery store in 10 minutes. There are still rural suburbs, but it’s much more expensive to live there due to the extra effort to get where you need to go.

There isn’t an easy way back since we let the auto industry have such a huge influence in politics, they’ve shaped the world, and it would take us decades and a LOT of money to revert the damage. We can still make steps.

HOWEVER, to bring the point back, we’re still in the 1910’s auto industry with AI. Are we going to let the AI industry get heavily involved in politics and shape our world into a worse one to benefit them? We’re at a point where we can reap the benefits, like with early cars, without the damage that came later
