I can fully understand the lack of judgement defence but you are right when you compare it to the whip rule. Is hitting a wheel a lack of judgement too?
I suppose the stipes are making allowances for a junior driver but that forgiveness is rarely seen for amateurs. If one of the amateur boys or girls had done this they would have got 6 months.
She should have been suspended, lack of judgement or not, for a couple of weeks for the sheer need to keep some integrity in the game.
