Hello I've been a lurker in here for some time now. This morning while doing my usual commute through central London, I was in the middle lane through Whitehall a white van man overtook me in the right hand turn lane and then swung back into the left hand turn lane cutting me up. Only to get stuck in traffic less than 2 seconds later. I pulled up and asked him if it was really necessary and suggested that he waited, I was actually quite polite. This was treated with a torrent of swear words about how I should have signalled while going in the lane that was going straight on. (?) My question is whether 'having a word' with drivers will actually change their behaviour in future or, as I suspect, will make them detest cyclists even more. Should I buy a helmet camera and adopt a zen like manner in cycling and just use the video afterwards?
