Keep the car consistent. Remember where the doors are, where the windows, pedals, etc. Music All players stand in semi-circle. One steps into the center and begins singing a song based on a topic from the audience. Other players tag in one at a time with songs inspired by the lyrics in the first song.
Game ends when players find a path back to the original song.
Support each other. Don't leave somebody hanging in the hot spot, especially if he doesn't know the lyrics.
