Sorry guys, but as a cyclist there is a lot of bad press about fellow cyclists. Now don't get me wrong some cyclists really cheese me off while im driving but as some previous posts state they cycle in large groups and don't move over when your behind. The police tell cyclists and horse riders to ride in big groups and to use as much of the lane as possible so the drive can see the cyclists and drive around them with a SAFE amount of space.
Thats the key point a lot of cyclists in my view ride their bikes unsafely in the eyes of a driver but put yourself in the shoes of the cyclist who is either just going home after a days work (just like you in your motor vehicle) or is doing some fitness training instead of paying out for a gym membership or just going for a steady ride to enjoy the countryside.
If they ride in the gutter its puncture central and drivers squeeze past with no consideration for the life of the cyclist, but when a cyclist rides in the middle of the road a driver will peep at them to try to move the cyclist out of the way. so why should the cyclist move over most of them own cars and to be honest has just as much right to be on the road as a car or a van
please spare a thought for the cyclist next time you pass one just give a little more room - they may come across as arrogant but treat them with respect and they will return the favour (most of the time) !
Cyclists will bunch together for a lot of reasons
1) you can go faster with less effort
2) you can talk
3) for cars its a shorter distance to overtake and therefore safer
4 ) no one will get left behind and potentially get lost
sorry to take the side of the cyclist but please see it from a real cyclists point of view, find a beer garden on a sunny sunday afternoon out in the sticks you'll see a group of cyclists, go over and talk to them and just ask why they do what they do.
