Is it time to start calling out bad cyclists?

I'm not sure what you mean here. I don't think that cyclists should approach in single file, you're welcome to ride in the traffic if you want. Nor do I think that they have to wait in single file at the junction, anyone who's going straight ahead can move over to the right of the ASL box. The only thing that causes problems is left-turning cyclists being on the right of cyclists going straight on.

If you do not believe they should approach in single file then leaving space for a fellow cyclist wanting to left shouldn't be seen as abnormal (as so many seem to).

I do see what you mean here. The problem is that you want others to take the lane and be a vehicular cyclist like you, while they want to make use of the cycle lane that's been provided. The merits of both positions have been discussed at length and in detail elsewhere, but I think it's worth reiterating that not everyone is comfortable being a vehicular cyclist and the lack of provision for them is one of the main things holding cycling back.

I'd like people to understand their rights, responsibilities and understand sensible use of shared space. Better than that I'd love to see more and more taking up cycle training. (I dislike the connotation of 'training', it needs a makeover to get widespread interest and less ego beating.)

No, but I've not seen those anywhere. Do they exist?

That's my point: drivers have no compulsion to give way therefore the most 'predictable' place would be further right. (Not necessarily in the middle of the motorised lane but somewhere that communicates something of your intent to fellow road users.)

Well if they motorist behind you in the situation described was going straight on, then I suspect his major irritation was sitting behind you when you could have moved over the left and made the turn with the other cyclists.

Huh?

But the lane that the bloke (who you had a confrontation with) was aiming for is delineated by a solid line. I agree that it's scant protection but it's not an unreasonable thing to do to position yourself so that you can go straight into it. You've not answered my question about what he should have done: if he filtered down the left in the bike lane and was aiming for the equivalent bike lane ahead on the left, your suggestion is that he should pull out into the middle of the lane and then back over to the left again. This seems really convoluted. Nor have you dealt with the problem that, had you been there first, he would have had to manoeuvre round the back of you to let you turn left. Another really awkward move.

Ok, I've not made it clear enough. In the mornings both of the cycle lanes (assuming you agree there's enough space for 2 breast) are majority filled with those going straight ahead. The only place to overtake going over the bridge is in the the next (non cycle) lane. As you approach the Northside you're looking for a clear gap to filter across the slower moving cycle flow going straight. What makes it complicated is that you're trying get across two lanes of traffic mostly going straight instead of one. Add to that few want to give way despite seeing a signal.
It's not complex: don't hug the kerb on approach to a junction - especially in the event you're not turning left. Don't forget^^^ there's no give way from motorised traffic on your right. Riding to the extreme right of the cycle lane is enough to tell most others that you plan on at least going straight. But yeah shit layout. A layout and policy brought to us by people that pay lip service to green/health/financial/safety issues for it's cyclists yet refuse to acknowledge the volume of cycle traffic instead opting for: what's best for motorised traffic.

Again I think this comes down to crap design. It's slightly ironic that the design of the bike lane brings cyclists into conflict not only with cars, but also with other cyclists who are acting like cars.

Hang on, I'm going mostly by the highway code and I'm fairly aware that I'm not a ford focus. There's a system for road use that mostly works.....amongst other road users. As a road user I see nothing wrong in passing slower vehicles on the right (where possible/sensible). Why do you think this strange?
