VIRGINIA POSTREL: Don’t Just Roll Back Back Fuel Standards. End Them. “The CAFE standards are lousy environmental policy. Instead of targeting the real issue — burning less gasoline — the mandates meddle in corporate strategy, impose enormous hidden costs, and encourage drivers to hang on to their old gas guzzlers. Republicans should scrap the standards altogether while they control the White House and Congress. The CAFE rules are a terrible way to achieve either fuel savings or lower carbon emissions.”
