Cars cost money. There used to be a time( and probably still are places) where African Americans biked everywhere. Why aren’t they now ? Probably infrastructure and I’m going to go out on a limb and say the stigma attached to not having a car. Having a car similar to other countries is a status symbol- kind of like eating meat. I also just think car culture will always be dominant in the states. It’s sad - biking is cheaper, better for your health and better for the environment.
