This is NOT how we taught. We taught that if you do not put a foot down you could be considered not stopping and putting your feet down is a clear indication you HAVE stopped with no questions.Stopping without a foot down is a skill taught by the Motorcycle Safety Foundation. It's a useful balance exercise. That ticket should be fought in court.
Me personally, I can not stop and balance that well, although I do know many that can. I think it is stupid, at least in this area, some people stop at 40 mph, worrying about a motorcycle and no feet down, when there are much larger violators out there.
