It is allowed by the highway code for cyclists to ride two or three abreast and this fill the road lane they are in. This is particularly so when it is tricky for motor vehicles to overtake them as it prevents dangerous overtaking. Many car drivers do not give cyclists enough room (i.e. enough to fall off their bike into the road without being hit).
Car drivers who expect cyclists to get out of their way and not use up road space are probably the same people who think pedestrians should step out of their way too when pedestrians have to walk on the road because there's no footpath, or when some driver has used the footpath by parking on it.
Cyclists and pedestrians have as much right to use the roads as drivers of motor vehicles. Why shouldn't some roads be closed to other traffic once in a blue moon so that cyclists can ride in a bunch for some particular reason? Roads are sometimes closed because of pedestrians demonstrations. What's the difference?
Yes, there are noisome cyclists. Probably in the same proportion as noisome drivers.
