Is it time to start calling out bad cyclists?

OK someone must know this bloke I met today on Camberwell Rd/Bowyer Pl junction:

I'm sure he was riding a Cinelli Vigorelli (possibly with a free wheel). If you do know him have a firm word. Cycling with him and another cyclist. Both of them keep RLJing where possible but haven't really gained any advantage and belligerently passing everything on the left. None of that bothered me but I was forced to say something when waiting at the junction pictured- to go ahead- you decide that the minibus already there, indicating left, so far in the left lane that you couldn't skateboard your way to the front. Yet you still felt obliged to try and force your way down it's side to the front for what? You got a bike length down and had to stop. Are you faster than internal combustion? Was the space there? I was genuinely scared for you and asked you why?

him: I was perfectly safe there.

me: But what was the benefit of squeezing in where you can't fit?

him: it's fine it couldn't get me. It was safe.

[[The most mental thing about all this was that you were going straight ahead!*]]

me: what about subsequent vehicles (from) behind turning left. Will they understand that you're going straight? Or could they left hook you?

you had a blank look in your face for a while and I hoped it would sink in but you insisted you were in the right and I have my view you have yours.
.......O....K......

Your positioning and worse your reasoning was truly stupid but I'm glad it didn't end up in acrimony. If I were your mate or family, I'd have slapped you for your unnecessary suicidal positioning though. Please apply some critical judgement on your maneuvers.

• The minibus left less space there than the bus in the image.
