The worst part of CAFE standards is that they KILL PEOPLE. Current estimates are that about 3500 more highway deaths per year are caused bu the light weight cars required by CAFE standards. This number will skyrocket when the Obama 50+ mpg rules are actually in place.
The dims don't care. What's a few more dead when your ideology has killed 100 million people? They have a fetish to copy every euro fascist style. Coercing people into tonka toy size cars is just one part of their master plan to control every part of our lives.
Unfortunately, the American public dry-humps "safety" like a three year old unfixed Staffordshire mutt will hit your leg.
So everything you can buy now is a g-d d--n Nerfmobile with crash bars and air bags up the yin-yang, adding weight and futzing up handling and gas mileage.
