Sir – As I cyclist, I would like to thank the 95 per cent of drivers on narrow country lanes who wait patiently before overtaking and who give me a wide berth when doing so.

But I am fascinated to know why it tends to be large four-wheel-drive vehicles and white van drivers who choose to overtake me on blind bends and who pass within a few inches of me.

Is it the case that people who drive such vehicles have never ridden a bike and so do not understand that overtaking this close causes a wind turbulence which can knock a bike over?

Perhaps they also do not realise how often a cyclist has to swerve out at the last minute, to avoid a deep pothole? But to strike a balance, I would also like to say how annoyed I am when cyclists choose to ride in large groups on narrow roads two or three abreast, ignoring cars queuing up behind.

And as for those city cyclists who ride in the dark dressed in black on black bikes with no lights? Have they never driven in cities and realised how invisible they are to others? Do they have a death wish? Or do they just assume they are immortal? I would really appreciate feedback from the cyclists and drivers to whom I have referred.
