Gentlemen,
I 100% agree that the activities depicted in this video are a huge problem. Its important that we educate people as to why these actions should be prohibited.
But...
Its equally important that the BMA be very clear that its not prohibiting a "type of person" but rather a "type of activity."
The job of the BMA, as I see it, is to continue educating motorcyclists about our responsibility as riders. If anything, this video shows that we could be doing this more effectively. Whistle blowing might not help us, in the long run.
My two cents.
