What's interesting is WHY cars have become bigger. The driver (heh) is the way the federal car mileage legislation formulas work. Simply, the large the vehicle, the worse the gas mileage can be. This is a reason why pickup trucks are large (not just F-150s, but "small" trucks like Toyota and Nissan). The overall area that the vehicle covers is part of the equation about what the minimum gas mileage can be. Smaller cars have to be very efficient compared to larger ones. So, cars and trucks have been drifting larger, longer, and wider in order for the automakers to cope with the demands of the CAFE standards and the market.
