Texas has pretty restrictive laws about parking minimums. It would be illegal to build a pleasant neighborhood (for my definition of pleasant) in Texas.

Also, negative externalities of Texas' built environment (lung disease, cancer, potentially more autism near motorways(still early stages of research) dead people on roads, inability to travel or perform basic tasks for those who can't or prefer not to drive, being impoverished by your automobile, and the potential collapse of global civilization due to climate change) are not priced in, so often the neighbors or the rest of the world are paying for those houses.
