Here's some food for thought from over 50 years ago: The original plan for the Gyronaut motorcycle was to have it equipped with two contra-rotating gyroscopes to keep it going in the intended direction. During WWII, Alex Tremulis had pulled apart the gyros in the German V2 rockets and immediately thought that if the gyros could be programmed to land in the center of London from Germany, then why the hell couldn't they be programmed to keep a car on the racetrack to eliminate spinouts. He was on a mission, especially following the 1964 deaths of Eddie Sachs and Dave MacDonald. The Gyronaut was to prove his concepts, but he couldn't get sponsors, Lear or Sperry, to jump on board. As deadlines neared, the plan had to eliminate the gyros, and switch from the Ford V8 to Bob Leppan and Jim Bruflodt's twin Triumph 650cc setup, calling it the X-1. The X-2 was to have the V8 and gyros and the X-3 the jets to go supersonic. Alas, only the X-1 was built. Still, pretty advanced thinking outside the box...
