To become a member requires the lady to hang 'em out for at least 5 miles (daytime hours) or a minimum of 10 miles in darkness. Now if she is behind you as a passenger, you can't really turn around sufficiently to get a good view so it's part of the initiation, that you must reach back with your (non throttle) hand and verify by touch that she is indeed got 'em out there in the wind.
Of course the reach back check should be done quite often to be sure she is not cheating with a cover up.
