While I don't understand a rule that lets kids lean out of the car, one has to remember that it is brought to you by the same people that think it's a good idea to sub-divide classes again and again and again. This way every other kid can be a "feature winnner." Now the dads can brag that their kid won 90% of the Senior Novice/ Medium Light 160/ World Formula/ Honda features that they entered. Never mind that the kid very rarely ran with more than two or three other competitors on the track at the same time.
