Is it time to start calling out bad cyclists?

I think we can all agree that if it is any kind of "long" vehicle we just MUST NOT go there unless we are 150% sure that we have time to pass it fully before it has ANY risk of moving.

agreed. I always remain behind long vehicles, even if I may well have opportunity to pass, I'd rather not risk it.

Perhaps I am just too conservative but the thought of ending up stuck to the left of ANY 4+ wheeled vehicle at a junction or lights, scares the crap out of me.

I'm not talking about being at the lights or at the junction, but a few cars back, and deciding not to keep filtering, therefore stopping on the left. sometimes there isn't enough space between cars to move out.

the stuff about predicting what's ahead - cars move. you can't always predict what they're going to do, so you're filtering, and then something happens up ahead to change the situation.

why is it scary to be 'stuck' on the left of a vehicle? genuine question, maybe I am missing something. so long as you are not going anywhere. particularly if it is not at the front/ at the junction. if you know you're in their blindspot, you just wait for them to move past, make eye contact with whatever's behind them and then move out.
