Similar to the Derive, except w/a car and a competitive element. I must give credit to Joe McKay as he told me him and his sister made this game up

The task is played as follows:
You and another person get in a car, you think of a place relatively close that you want to goto, they also think of a place they want to go. Neither of you reveals your destination and the point of the game is to guess the other persons destination or get to your own. At every intersection, you take turns either saying "Straight" or "left", while making the appropriate vehicular maneuvers. The trick is to not give away where your going to exactly, and maybe even starting by going in the opposite direction.

Game need not be played w/a car and can easily be done on foot, but the original is in a car.
