Most car dependent places in the US don't enough money to actually repair all of the roads and infrastructure that they have built out. Also, most places there is no option but to drive because of zoning practices effectively banning mixed use. Suburbs from the mid 20th century on are all designed for cars and cars alone. Giant consolidated schools are put far away instead of the traditional smaller schools closer to where people live so kids have to be driven by bus or by parents. It was not always this way but it has indeed been forced by a design choice in how suburbs are laid out.
