Dr. Robert W. Crandall, Barry Felrice, Sam Kazman, and Dr. W. David Montgomery. “Fuel Economy Standards: Do they Work? Do they Kill?”. Heritage Foundation. 8 Mar. 2002 – “CAFE is a solution in search of a problem. Is the problem global warming? Is it energy security? Is it traffic congestion and air pollution? Or is it simply the envy of some people who can’t afford to buy large SUVs? I think that I can say confidently that except for, perhaps, a subset of that last problem, CAFE is not the right solution to whatever the problem advocated is.”
