.....cycling with no lights in dark clothing. You can just about see them on lit roads but on the cycle lanes where there is poor/non existent street lighting and they're really difficult to see. They don't seem to have any road/lane sense and weave/wobble unpredictably. How do they expect other road users and cyclists to see them looming out of the murk? It doesn't cost much to put some lights on so why ride without? Also experiencing undertaking cyclists when I'm trying to keep a decent lane position. I'm on a slowish bike so don't do primary often but occassionally I am further out than usual for various positioning reasons and get these idiots undertaking. Then get other muppets passing really close on the outside squeezing between me and faster moving traffic. One slight adjustment to my position and we would collide. They obviously think they're totally in control of the overtake which they're not of course riding that close. Touched shoulders with one overtaking me last week. He thought he could squeeze past when there wasn't enough room just as I'd moved over to avoid one of those large wet manhole covers. It's good to see so many cyclists now riding to work but a fair few of them are nutters and as unpredictable as bad cagers.
