The automobile has been on the verge of being reinvented practically since it was invented. Cars that would float and fly, cars that would walk, cars that would cruise like bubble-shaped VIP lounges: Surely a brand-new car was right around the corner, or at least a couple of years away. Problem was, the irreducible requirements of engine, transmission, suspension, and fuel tank, and all the mechanical linkages involved (pedal to throttle, driveshaft to wheels), dictated much about not only how a car would function, but how it would look.
