 The flying car in this film starts plummeting toward the ground,  only to stop shortly before making contact because it ran out of  gas. This is a reference to the classic wartime cartoon  _Falling Hare (1943)_ (qv), in which Bugs Bunny and the Gremlin are  in a plummeting plane that stops just above the ground at the end of  the cartoon for the same reason. Furthermore, one of the other cars  in the film is a Gremlin.
