The cost of giant road network connecting a patchwork of exurbs is vast. If the exurbs wind-up being considered a luxury and inhabited by those who can afford, the cost per-person goes up. Even more, if the US gets rid of its extreme wealth/income imbalance, the number who could afford it would go down even further. Essentially, Exurbia is millstone around this country's neck, effectively moving the place palpably to disaster via fire, unhinged ideologies and generally unsustainable infrastructure.
