    Why not make it a two peonged attack against heavy vehicles?

    If we correct the perverse CAFE standards that push manufacturers to increase the size of their cars, the problem largely solves itself, without pissing off consumers.

    The standards currently require proportionally greater decreases in emissions on smaller vehicles than larger vehicles. Manufacturers are deliberately increasing the sizes of their vehicles to qualify for the easier standards.

    Requiring smaller decreases on smaller vehicles will reverse this trend. Manufacturers will need to spend considerable resources on R&D to improve the economy of larger vehicles, or slim them up so they qualify for a smaller category.
