Well yes and no. I appreciate your point, you have every right to make it, but coming up behind a group of cyclists spread out using the single lane and then coming on a non bike forum to point it out in the way you did - Look at this. everybody look at this. These cyclists taking up the whole road etc etc. does imply you came up behind them and i suppose anyone else int he car with you got an ear full of 'look at this, bloody cyclists. I cant overtake. damn them, move over move over' etc.
Heres a pic of a project down in London. They surrounded a bike with a car sized cage.
Say those cyclists you came across all had these cages on. What you'd have is a line of slow moving traffic correct ?.
So its not really any different to that, and any overtake needs the overtaker to only be able to do so when the road ahead is clear, and straight without bends. You might have to wait a few miles before that becomes possible.
