Are you blind?
Did you actually READ the article? Seriously, please try to absorb all the information in an article before you comment to avoid looking like you do now. The article clearly states - and can be backed up with evidence - that consumers ARE buying smaller cars and enough of them that auto manufacturers are concentrating on the market and expecting profit margins to decrease because of it. So, your comment of "If people wanted smaller cards, they'd buy them" is a bit idiotic in light of the entire premise of the article.
Regulations aren't dictating what type of car you can buy. They are simply dictating an overall fuel economy average and emissions requirement covering the entire range of vehicles a manufacturer sells. Thus, they can continue to sell gas-guzzling, pollution machines like the Hummer, Chevrolet Suburban, and the like, but they will have to counter such vehicles with a strong small-car offering to balance the numbers. If they have trouble doing so, that is the manufacturer's issue, not the problem of the people who want to buy them. I'm strongly in favor of gas guzzler taxes as I believe if you want to destroy the environment for my children and grandchildren while we try to save it, you should have to pay for doing so. Hitting people like you in the pocketbook is the only thing you tend to understand, so let's make it hurt. Many other things hurt me, especially the belching exhaust from your SUV since I had a lung collapse and had to have a chunk of it removed. My low-emission vehicle doesn't hurt you, but your noxious polluter DOES hurt me.
Corporations have shown that they only care about the bottom line over and over and over again. They won't regulate themselves. Therefore, regulations such as the ones mentioned are the one and only way to force these corporations to take responsibility for their actions and their impact on the environment. Thus, regulations are a necessity, whether they, or you, like it or not. You can suggest whatever you like, but, as you mention, you may receive a label for doing so. One moronic policy suggestion does not a fascist make, so it's unlikely I would use that terminology unless I saw you regularly suggest fascist policies and ideologies (which is also unlikely as I just don't read many articles on Smart Planet anymore because it's been overrun with people like you and Andornoe advocating for environmental destruction on a site designed to advocate for environmental preservation).
