There are multiple studies and historical accounts documenting exactly this TsunamiFury. Car lobbies are actually clearly tied to many city planning decisions, combined with white flight and corresponding government loans to create suburban communities that essentially cut others out.
Additionally interstate commerce in a comparatively intensely large land mass like the US did create a need for additional transportation, but the sprawl has indeed been very much tied to the factors PaulDavisThe1st and others have pointed out. Its not 'not liking' each other. Its money + racism + poor representation of the populous. Like a lot of things.
What studies or books lead you to your conclusion?
But I live in Pacific Heights, one of the most desirable old world communities in America, and it’s mostly empty and full of ghost capital homes.
People like it for a while but they leave for the suburbs pretty fast and go looking for elbow room away from others. And it’s mostly because the energy under the surface of the beautiful homes is rude, selfish and inconsiderate. From the owners to the workers that come to service the homes. Regardless of class we are really angry people.
but ...
The current situation in uber-expensive real-estate markets when it comes to high-end housing should not be over-interpreted as having more to say about what most Americans want from the places where they live.
Pacific Heights current situation is also very similar to wealthy old neighborhoods in cities across Europe. London at the very least is full of such examples.

>> We would have built better cities if we wanted carless communities. But we didn’t and still don’t.
Blockbusting was a real phenomenon in which real estate agents would move a black family into the neighborhood to get white families to fire sell their homes, and it worked because they could no longer legally isolate minorities from their children. https://en.wikipedia.org/wiki/Blockbusting
We know that this happens today, even with minority groups that are affluent and do well in education metrics. https://slate.com/human-interest/2015/07/silicon-valley-whit... (And before anyone accuses me of "wokism", the original story was broken by the Wall Street Journal, which is decidedly not a "woke" publication.)
Older US cities have many of the same characteristics as cities in other parts of the world. Those characteristics can vary, from small single-family homes tightly packed into a walkable neighborhood to large scale apartment dwelling with city squares and boulevards nearby.
Americans used to build cities this way. Whether it was Moses or the emergence of a general dislike of each other, or a multitude of other possible reasons, we generally no longer do.
Moreover, many of those older city neighborhoods are considered extremely desirable to live in, even today, so much so that they have become very exclusive areas available only to those with plenty of income or wealth. That doesn't imply that most Americans would necessarily make that choice even if they could, but the continued elevation of housing costs in the best of these "old world" neighborhoods suggests to me that your thesis is at best incomplete and at worst just incorrect.
