I love to drive therefor I buy a car I love to drive.
America is largely rural. Comparisons to Europe aren't appropriate outside of the proper metros.
My "city" of 5K is considered "urban" according to the 2020 census. There are nearly zero services in this "city", only a couple of restaurants, the largest employer is the school district, and it's surrounded by farms and mountain forests. It takes 15 minutes by car to get to the next town over on a two lane highway.
If you want to get to any real city, you're looking at a 30-45 minute drive at highway/freeway speeds.
So yes, there may be more individuals in "urban" areas, but not all "urban" areas are functionally urban. My "urban city" per the 2020 census is no LA, Austin, or Portland.
Bicycling with little kids is just not practical for a lot of it, and the nearest bus stop is a four hour walk (12 miles).
Do large cities and suburban neighborhoods deserve public transportation? Sure. Is that a universal answer? No. Not even close. There are farm fields out here larger than many towns. Roads, vehicles, and fast on demand transportation are a necessity for the geographic super majority of the US.
