We were sent this clip by Chris Impey, who says the incident happened on London's Embankment around Chelsea Bridge. Mr Impey said he was overtaken by the offending cyclist so closely that he was almost knocked off. He told road.cc: "The cyclist then tells me the reason he did what he did is that I was in the “middle of the road”. I respond that I was in a primary position; in fact looking back at the footage, I think I may even have been in a secondary one. I was certainly no distance from the kerb and had just overtaken someone else."

As another cyclist challenges the overtaking cyclist at the first set of lights, he shouts him down and then Mr Impey continues to remonstrate with him further up the road: "I try and point out to him that this is the kind of justification give by drivers who commit close passes, but he just keeps telling me to ‘“read the Highway Code”; although he has clearly forgotten to read the part about treating other road users with care and respect. We continue to discuss the issue as we ride along - he goes on about my positioning, that he is a driver (not unique among cyclists I believe) and with me trying to make the point that I just want to get to work safely."

Mr Impey continued: "As a cyclist, I’m used to getting bullied by cars. I’ve almost become inured to it. For a cyclist to do this - and he was very close to causing an accident - I found shocking and depressing. This is a dangerous stretch of road, without any kind of cycle infrastructure and often with (literally) heavy traffic. I like to think that people on bikes are looking out for each other, not trying to cause each other harm."

Have you experienced any similar acts of aggression from other cyclists?
