How about getting the government completely out of car manufacturing? No CAFE, no safety standards, etc. Let the market (the people) determine what they want to buy. If they want safety, they could by a car designed like a tank. If they want mileage, they could buy a shoebox on a rollerskate (which Government Motors will soon be building). If they want a 500 h.p. 1970 body-style Hemi 'Cuda, let it be.
Basically, let the people decide what they want. After all, this nation was once free; does anybody remember?
