Cyclists are at the centre of a national debate! On the one hand it goes without saying that cycling has enormous environmental and health advantages. On the other hand cyclists are extremely vulnerable and there is of course an ongoing risk/benefits assessment to be made between the advantages to the environment and personal health from cycling, and the possibility of suffering a serious injury. This is of course a political matter and no doubt we all agree that the road should be made as safe as possible for cyclists. Nevertheless cyclists do suffer serious injuries.
