It’s not just oppression against “other forms of transport;” it’s literally classist and (to the extent that race corresponds to class, which is a lot and on purpose) racist. A lot of these zoning laws about minimum parking requirements and minimum lot sizes date back to a time when United States government policy was explicitly designed to perpetuate segregation, and forcing every new parcel and development to be large and expensive enough to be unaffordable to most black people (because they were, and still are, poorer on average because of other institutional racism) was a part of that.
