Burst their ball!!

Yeah, it drives me insane too - but they are kids....what can you do! They dont understand, and a lot of the time their parents dont either, because they dont look after their cars. They look at you as if you have two heads if you say anything!!

You'll have to priorities which car gets the most protection....I try part hers in the line of fire, as its a bit rougher around the edges than mine, so dont mind it getting a bit worse! :P
