Well, many (not all) want car-only infrastructure, but they've also been unable to realize the true cost of their decisions, hence South Florida will be underwater. It costs too much money to build and maintain the infrastructure that would be required to maintain the lifestyle. So far things haven't gotten too bad but insurance companies are beginning to refuse to insure homes in Florida and so it has been left to the state to subsidize at a loss. Similarly as the state continues to build out unmaintainable car-only infrastructure and attempt to keep much of the state from "going underwater" it'll require either transfers of wealth from other states or increases in taxes. Neither of those proposals are politically viable either, so eventually the infrastructure just won't be maintained.
