My data is the far lower prices for equivalent sized townhouses (homes that share walls) compared to detached single family houses, the increasing volumes of larger vehicles sold over smaller vehicles, and higher proportions of children in suburban areas compared to urban areas.
People like space, people like choosing who to share space with, and people like feeling more powerful (sitting higher up in bigger vehicles).
In my area, Zillow shows sold home prices for comparable townhomes vs detached SFH at roughly 30% lower price per square foot. People are willing to pay a couple hundred thousand dollars to not share walls.
>Those we designed and pushed by the car lobby and the US made it illegal or very unprofitable to build any alternatives
The US (federal government) didn't make it illegal or unprofitable to build more dense housing.
Local city and county level voters made it illegal and unprofitable, because more dense housing means poorer people, and poorer people means schools with kids who have poorer parents, which typically means a peer group that may not perform as well.
