I think you are misunderstanding my viewpoint a little - I'm not saying he should have been using the cycle lane but taking the various factors into account its obviously there for a reason. He is however cycling in an advanced manner on a non-trivial bit of road - traffic conditions, layout, etc. and IMO should take on board that not all other road users will have the same level of ability especially combined with the reduced awareness of what is going on behind him (when he isn't keeping up with the other traffic flow) - even taking muppets like the van driver out of the equation. I don't think it unreasonable for a bit of responsibility to go both ways.
I don't really expect many cyclists to see my viewpoint mind,
No, because what your suggesting is that he cycle at 5mph, hanging to the kerb, because of inconsiderate motorists.
