Is it time to start calling out bad cyclists?

i dont think they are all silly, some are just using a bike to there advantage, why ride a bike and do the exact same thing you would in a car? (following the rules of thr road i mean) i know i ride becouse i can do things i cant in a car and get away with it easily without corsing any hassle to any one, unless i want to :P

but ye some are pretty dam stupid

Because you are meant to, and by not doing those things you are much safer. Since I had cycle training, I've become a much safer cyclist, no rlj-ing, better road position, I hardly ever undertake any more.
