We were watching this movie tonight. If anybody doesn't know it is about a man who modified an old motorcycle to break a land speed record, the motorcycle had a full fairing to make it a "streamliner". At one point in the movie he is going at high speed and the bike starts wobbling. Later he is explaining to a group that he needs to have the center of pressure behind the center of gravity. Of course we all understand that at high speed a wheeled vehicle needs aerodynamic stability just like a rocket does. I thought it was a very unusual detail to include in a movie. I remember reading in a car magazine many years ago where the writers were modifying a firebird for a speed record attempt. They wanted to be sure to have plenty of traction at high speed on the salt flats so they put a lot of weight in the trunk. Is everybody thinking ahead here... it did just what you would expect and ended up at high speed not going nose first down the track. When I read that I was thinking "well duh, I know better than that".
