Earlier quoted context omitted.
That makes no sense... US cities are super lucky to have such wide streets. If they WANTED to they could easily make dedicated bus and bike lanes that are safe. It easy they have so much space. European cities have to almost ban cars, to make room for bikes... This is a political issue, where Americans choose not to do something.
The US has plenty of space for bikes and pedestrians, but being a cyclist or pedestrian makes less sense there because the cities are so spread out. All the space taken up by those highways and parking lots mean that the places people actually want to go to are much further apart.
Parking contributes, but it’s mostly that American towns have at most a few blocks where European-level density (3-6 story buildings directly adjacent to each other) is permitted.
Good luck prying the detached house with a backyard out of the typical American family’s hands. Good luck getting them to consent to a multi family structure next door.
