There is no way that you can class that as a joke gone wrong,that's down right evil. If someones at that sort of game in a national,it means that you can't let your car out of your sight for even a minute.

Can you even imagine the stink that would result,if that was done to one of the top named drivers?

Racing is a nerve wracking trial as it is,without having to watch every Tom,Dick and Harry,just in case he's up to no good. I seriously hope that someone catches the culprit in the act,and deals with him accordingly.
