What are the rules for your car?

I'm currently on page 4 of a rulebook for my car. I got my license a little while ago, and my friend and I decided rules needed to be made. We have wear seat belts and the rules of shotgun, yellow car, padiddle, punch buggy, and the game where you see the same type of car as yours. WHAT OTHER RULES ARE THERE? The funnier the better.
