Here we go. It's the latest 'how cyclists should use the road' debate on social media. This photo came from a guy saying he sometimes pulls over to let backed up traffic through. 'Rush' posed the question: why, even if you don't have to, you wouldn't move off the road to let the queued traffic pass?

Some questioned the accuracy of the situation...had he really been sat behind the cyclist for two miles on what looks a reasonably wide road? Others asked if the lorry driver should also pull over to let the car drivers through?

When pressed, Rush said: "Periodically, yes [cyclists should pull over to let traffic past]. The Highway Code does not compel, but it wouldn’t hurt. It’s good road craft, that’s all. The chap was cycling along slowly, creating a needless tailback." And in reply to another question...

"The rider didn’t have to, but should have used road-sense and should have simply pulled over and would have received many friendly toots of cordial appreciation. Now what’s so difficult about that?

"Being a thoughtful and courteous rider isn't a completely selfless act, riding etiquette can cheer up those around us and generally create a more enjoyable, harmonious and stress-free relationship with road users."

Here's some of the discussion and reaction...
