Recently I was driving down the Dock Road behind one of those lycra-clad dickheads who believe they are too professional a cyclist to use the excellent cycle path that was installed along most of that road at great expense. 
So, we're all crawling along as he takes up most of the road as the cycle path goes unused. I used to do 200 miles a week for work on a bike, so I know all about the difficulties involved, but cyclists like him give the rest a bad name. Not only did he shun the excellent cycle path, he also decided to ride like he owned the road too.
I get that some serious cyclists need to use the road, I suppose if you're training for a proper race, then you need to replicate the conditions, but then again, if they're doing less than 30mph and holding up traffic, they're not really a serious cyclist? I also get that some cycle paths are unfit to use, but if you aren't going at the same speed as the traffic and the path is fine, use it. Just because you can do something, doesn't mean you should. Our kid shared an image from his dashcam, fella in lycra on the A31, problem is, this is the main trunk route from Surrey to West Dorset, a very heavily used dual carriageway, you've got HGV's doing 56mph, cars doing 70mph, he was risking his life for god knows what reason.
I also hate the ignorance, if there is a queue, just pull in and let them pass - when the speed limit on single track roads was 40mph for HGVs and 50 or national for cars, if I got a queue forming behind me, I'd pull over every now and again and let the queue pass if I could, since it's been raised to 50mph, I don't now, as I find most cars don't go over 50 on those roads anyway. Just show a bit of manners, pull over, let the faster traffic pass and there's no issues, no dickheads being twats to the cyclist and no anger from drivers to cyclists. Cycling should be encouraged, but ride responsibly please.
