As a driver I have come across instances of dangerous, careless and thoughtless behaviour by cyclists. The worst was when on a quiet, winding country road a cyclist suddenly appeared in front of me on the wrong side of his road - clearly cutting a corner to save slowing down. We did not collide - but this was a significant factor in my purchase of a dash cam.
Groups of cyclists ride three abreast or string themselves out - in both instances they make safe passing difficult or impossible.
Cyclists have every right to be on the road and they deserve to be treated with care and respect. But in their turn they should recognise that sharing a road with motorists bring with it responsibilities as well as rights. Perhaps we should consider whether adult cyclists should carry compulsory insurance.
