Tearing down is a lot easier than building up. We leveled massive neighborhoods and rewrote how transportation infrastructure works in the US due to the car. Not to mention everything is much much more expensive now than it used to be and the political will to fix things isn&#x27;t their. You&#x27;ve also got decades of voters who think in terms of the automobile. People in their 60&#x27;s, 70&#x27;s and 80&#x27;s remember denser more urban cities where cars didn&#x27;t dominate, but those people moved to the suburbs in their adult-hood and raised kids in the burbs who then raised their kids in the burbs and so on. Car culture is going to be here for a long time and the damage it has done will be slow healing because the people who could speed up the change the most have had an auto-centric world view from childhood.
