Umm, Adrian, dear...
I was driving slowly along a winding local road in the middle of a town the other day - and four idiotic cyclists went peddling hell-for-leather past me spread out on the wrong side of the road *AND* on the pavement, heading into oncoming traffic and weaving in-and-out of legally parked cars and around pedestrians - and then verbally abused the driver of an oncoming car that nearly hit one of them as he came off the footpath onto the road in hidden by a parked car.
Just to add to the above, when they came to a T junction, not one of them bothered to stop at the halt sign,and went straight across, forcing a car driver to carry out a full-blown emergency stop - and again giving the usual verbal abuse to the driver who had just managed to avoid killing them as a result of their stupidity.
Were these cyclists children? were they hell, all adults who should have known f**king better.
So with regards to the "Umm, Mervin, dear..." end to your post, why should motorists have to take responsibility to look out for idiotic cyclists who think that the highway code and laws don't apply to them - and that every road and footpath belongs to them to cycle on just as *they* please - along with the attitude of 'f*ck everybody else?
