Ban Scalextric F1?

ok, at our club the f1 class has just turned into destruction derby, you need a new car every 3 weeks, a complete rebuild every week... now the ninco cars arent causing many problems.. the odd crash here and there, but any scalex models no matter what is done to them theyre just so un predictable they are considering banning scalextric cars.. i can see why, because i have one of the offending f1 cars, but if it does go off pieces go everywhere ive had the car for 3 weeks now the body is completely destroyed, and im on my 3rd chassis. so the question remains: should the scalex cars be banned or not? id like to hear the opinions of other people
