I don't beleive racing rules are that strict.
If you excersise plenty of common sense and respect for fellow racers we wouldn't even need rules.
But you have to outline every aspect in the rules because when someone messes up, they say " uh uhhhh, where is it in the rule book?"
Its the same reason there are laws about not having sex with sheep and tags on your hair dryer telling you not to use it in the shower.
