I was raise in Brooklyn, NY and we used to play that game on roadtrips in the family car. We also played a different version of this game, that we called “punch car” in which you would slug the other player each time one of you spotted a Volkswagon Beetle car (which were also known as Volkswagon “Bugs” to us). But first, you would point at the “Bug” and yell out “punch car” before throwing your punch. We had fun playing these games until someone would punch to hard and a fight would break out in the back seat that usually ended when one of our parents would reach back from the front seat and slap everyone!!! Ha, Ha. I really miss the old days.
