Earlier quoted context omitted.
Depends where you live. That's a broad assertion to cover a wildly divergent spectrum of community types.
It’s an easy assertion to make because even car transit itself is better in places that aren’t car centric. (Because fewer people are on the roads, and roads are much safer.) https://youtu.be/d8RRE2rDw4k
Population density in the US is 34.05 people per square kilometer.
Granted, a huge amount of the US should probably be discounted for a more realistic comparison (e.g. unlivable regions, BLM / park / national forest, and massive amount of farmland), which would bump the number up.
But we're still probably going to need some adjustments going from a country you can drive across in about 4 hours, to one where it would take 40+ hours.
