I'll be prepared to be told IABU as I have often heard cycling rules spoken about on here that I didn't know but I'm not sure how I could be!
Approaching a roundabout today, there was a long line of traffic coming the other way.
Suddenly as I was getting close to the roundabout a group of cyclists one after the other came around the traffic (on the inside and on my side of the road). I very nearly hit them and got a mouthful of abuse off one of them.
I couldn't see them coming round the cars (couldn't see them over the top of the cars and there is a building on the corner of the roundabout too) until the first was in front of me on my side of the road. I obviously did manage to stop in time.
Should they not have gone on the inside (pavement side) of the traffic if they wanted to get round and surely not on the other side of the road?
