So, this has happened a couple of times... I stop at the redlights in an ASL in central London, along with 10 other cyclists. As they are all converging from either sides of the lane, some pull up close alongside but are not always then poitning directly ahead. When the lights chnage, I've nearly been knocked into other cyclsists by the wobble of someone who had stopped very close to me and pulled away at a funny angle or wobbling into me. Is this a 'thing' or have I just been unlucky?
