As I'm sure the commentors here from outside of the U.S. can plainly see - it's going to be a long road to get regulations in place to somehow incentivize smaller vehicles (and that's assuming we ever have a functioning government again). For Americans, a lot of our self-image/worth is tied up in the vehicles we drive. I suppose it's a combination of cultural history (hyper-individualism) and decades of marketing and advertising from auto manufacturers.
