I just revisited this thread and would like to thank @doog442 for his even-tempered and stalwart defence of common sense and decent behaviour among road users of every kind. Like all of us here, I enjoy driving my Lexus, but I am in the minority I think in riding a bike, a lot, in London and its environs.
As a driver, I appreciate good manners and good judgement by other road users. As a bike rider, it makes or mars my day — and I live in hope it will not destroy it. I write as one who has held a driving licence and used it for more than 50 years — and, of course, ridden a bicycle for even longer. I hope to be able to do both for a good few years more. The guy on the bike in front of you is another human like you. Just take your foot off the gas. Be cool, be nice. It's not a problem.
