Lamborghini Chess Game
The drivers need to know how to handle a stick shift, as some of the cars might come with manual transmissions. The game is to be played just like a standard chess one, but the pieces will be replaced by cars.
And the time is limited only by the amount of fuel left in the tank - the engine is running all the time, but the tank is filled before each game starts. Whoever wins, stays in and gets to move his pieces during the next game, while the loser has to wash the cars after the day is finished.
