  1. Increased fuel economy can be achieved by:
    * increasing taxes on gasoline to encourage people to drive less
    * insisting that cars be engineered to get better gas mileage
    * exploring alternative energy sources that DO NOT use food crops
    * greatly increasing public transportation

    In my experience, most people by SUVs and large trucks to appear macho or keep up with their neighbors.
