Thats not true, i often drift round druids at brands. Theres a 6R4 whichs is often at brands which always drifts, hes been there for years and no ones stopped him. Youre going on set down rules, reality is youd never get black flagged unless you were obviously a risk to yourself or others.
Normally what happens is theres 2 track sessions, 1st session experts are sent out first then intermediate then beginner, 2nd session everyone goes out at the same time so passing like that is what happens.
