Remember the 70s and the energy crisis which spawned the sub-compact car? Can't we just go back to that instead of giant vehicles with an auto loan that is bigger than the mortgages of the 70s? Better gas mileage, traffic moves faster, more parking spaces, AND they are light enough they can handle driving in the snow far better.
