Again you’re talking about dense population centers. Americans for the most part don’t want to live like that. They want stand alone houses with large yards in the suburbs. Those are not densely populated enough to make walking to all the businesses you need feasible. Rental cars are a pain in the butt. Spend an hour getting one. You need someone to come with you to drive the vehicle you arrived in back or pay for expensive parking or an Uber. Repeat for when you drop it off. They kill all spontaneity. That being said I would love to have a better train network in the US, just not at the expense of roads.
