I have an issue with cyclists in general. The Government is bending over backwards to encourage cycling but not placing any restrictions on the cyclists. They are not registered, they do not have to purchase insurance. Insufficient provision is made for them on the roads.
They spend maybe hundreds of pounds on their bike and clothing but never spend a few pounds on a bell - just not cool enough for them! If you are hard of hearing or your clothing perhaps rustles as you walk, you don't hear them until they are right behind you - at best this simply frightens you, at worst you inadvertently take a step to the side and they collide with you. They always assume you are going to walk in a straight line.
On country roads they ride 2/3 abreast so that cars can't pass.
We lived on the edge of the Peak District and were keen walkers. I have lost count of the number of times cyclists have nearly ridden into me on walking paths. If there are several of them the first one never calls out to warn you that there are more behind - on one occasion as I was walking uphill towards a bend, I had to jump into the hedge 3 times to avoid being run over by a group of cyclists riding downhill at great speed. The Monsal Trail, for instance, used to be a good walk for people who couldn't cope with the hills any more, but they opened the tunnels up and now cyclists flock to it because they can ride for many miles unimpeded. Can you imagine walking through a dimly lit tunnel and having a bike come up behind you at about 25 kmh? It's very scary.
Cycling is being promoted for health reasons, but walkers have been following their sport also for health reasons for years, yet are being driven off their designated paths by arrogant cyclists. I was once walking along the Regents Canal when I was bellowed at : "Get out of the way!" by a female cyclist who certainly didn't slow down for me.
On the odd occasion that a cyclist rings a bell to warn me of their approach, I always thank them, but it's quite a rare occasion.
I have found cyclists to be very arrogant in the main, and obviously realise they have the encouragement of the powers that be and that the likelihood of them being prosecuted for riding on the pavement, for instance, is very unlikely.
Middle aged men in lycra are definitely the worst though.
