I think you're sort of missing my point.

After decades of ignored negative externalities from unchecked suburban growth and car-culture are coming to an end. As populations decline and temperatures increase places like Dallas and the wealthy suburbs around it that you mention will have less and less relevance.

There isn't going to be a future where the citizens of suburban Dallas are enjoying Starbucks coffee in single-serving cups delivered to them in Waymo vehicles. It isn't viable to just paper over unsustainable nature of these places with self driving cars and ignore urban environments and mass public transit as the comment that started this thread suggested.

The only places that are going to survive what is coming are ones that are dense, well managed, and sustainable.
