Cyclelab cyclists

On any given Saturday Troupant Avenue becomes almost impossible to navigate due to the swarm of cyclists who make use of the road.
They have no regard for the rules of the road riding three or even four abreast and refusing to give way to motorists. Any attempt to point this out is met with abuse.

I understand they have a right to be on the road but as with any road user they must obey the rules.
Complaints to the cyclelab directly fall on deaf ears or are dismissed out of hand.
