I'll go along with 'misfire' for the "%#@&/×+" part of G-Force's post.

I've been driving cars and riding bikes for well over half a century and I can't ever remember encountering two-abreast cyclists who wouldn't give way to a car behind once they'd become aware of it.

As DtG pointed out, upthread, there are poor standards in all walks of life and it's the badly behaved ones who get noticed. I am surprised, however, at your claim never to have encountered the problem set out above.

The main road I live on connects the roads coming from the countryside to main roads leading into either side of town. Although we now have a by-pass, it still carries traffic of all sorts and is on a bus route. More than once, I have been in my front garden and seen a group of six or more lycra-clad cyclists go by, two abreast, chatting away, seemingly oblivious to the queue of traffic behind them. I have driven behind such a group as they left the village into the 40mph section of road, still two abreast and ignoring the segregated cycle track.
