Over here, there are a lot of keen cyclists/triathelete's. And some good points made above. Thing I don't seem to see happening so much now, is we always, especially in big pack or group of 3 or more, always yelled out instructions to the rest of the group, about cars from behind or in front, or oncoming, potholes (hand signals), which elleviated any kamakazi's amongst the group. Grouped them in, to keep them under control. We have the same issues, with absolute nutter temporary citizens, of both 2 and 4 wheels - everyone just needs to be more tolerant of others around.
