I don't want to escalate this into WW3; however, I learned early in my driving history, that children, cyclists, horses etc can be counted on to move suddenly; I was driving (on L plates) quietly past a string of horses being ridden along the verge, when one of them chose to swing and rear - my car passed under its front hooves. We all, I think, have dire learning experiences, especially in our early driving days, and it's sheer luck if they do not cause an accident; but the essential thing is to learn from them. A horse can move or a bicycle rider can sprawl, up to about four metres sideways if something goes wrong, so I reached the conclusion that it pays to allow that much clearance when one passes them.
