I can deal with cyclists who are actually travelling somewhere, but the ones who load up the roads at the weekend purely for their own amusement can do one. A ‘peloton’ invariably goes past my house every Sunday around 0700, and apparently, its members shouting to each other as loud as they can is part of the deal. Sorry YOU can’t sleep lads, and that your only solution is dressing like a bell and getting on a bike, but the rest of us are trying to get some kip and/or trying to use the roads for their actual purpose, not as a race track.
Another thing that I see a lot of and also gets on my tits is, when there are group of cyclists, and instead of riding behind each other in a single file they spread out across the road side by side, or bunch up in a group, therefore taking up the whole lane and making it more difficult and dangerous to overtake them.
