Trivia: The logo on the tank truck is "7 Sisters Oil", reference to a conspiracy theory, popular before OPEC-conspiracy theories took over, that Standard Oil and six other companies controlled the world oil market and bought up and suppressed 200-MPG carburetor and so on to keep oil prices up.

Trivia: You might have to look close, but the Gyro Captain's copter is completely covered with pornographic pictures. It took many viewings for me to notice this. Apparently he's very sexually motivated, as later in the movie he complains that the only thing he really misses from the old world is lingerie, and the only reason he joins the escapees in the end is because he wants to be with the cute blond girl.
