Standards are slipping, but no more than driving standards are falling - it's a sign of the times I'm afraid. Cycling proficiency tests in schools/Cub Scouts/Brownies etc will take care of educating the children, but the majority of offenders I see are adults. How does one educate them on the etiquette of cycling?
