My friend said every time they see a car from another state they're suppose to call it then hit the top of the car. The last person to hit the top of the car has to strip an item of clothing. The one who becomes completely naked first, loses.
One time when I was in elementary, when we were going in a field trip, our teacher asked us if we(me and 3 other of my classmates) would want to play "bumper cars" on the street. So what she did was we drove fast and started swerving fast left and right for a long time until we saw another car it was a lot of fun
