1933 Fuller Dymaxion

Designer-genius R. Buckminster Fuller was one of the century's great nutjobs, a walking unorthodoxy who originally conceived of the Dymaxion as a flying automobile, or drivable plane, with jet engines and inflatable wings. It would be one link in his vaguely totalitarian plan for the people to live in mass-produced houses deposited on the landscape by dirigibles. Okayyyy...Deprived of wings, the Dymaxion was a three-wheel, ground-bound zeppelin, with a huge levered A-arm carrying the rear wheel, which swiveled like the tail wheel of an airplane. The first prototype had a wicked death wobble in the rear wheel. The next two Dymaxions were bigger, heavier, and only marginally more drivable. The third car had a stabilizer fin on top, which did nothing to cure the Dymaxion's acute instability in crosswinds. A fatal accident involving the car — cause unknown — doomed its public acceptance. Though unworkable, this three-wheeled suppository was the boldest of a series of futuristic, rear-engined cars of the 1930s, including the Tatra, the Highway Aircraft Corporation's "Fascination" car and, everybody's favorite, the Nazi's KdF-wagen.
