I reckon, if you are going to be riding on a bike path, you would only be going,10,15ks max, and with no obstacles on bike paths it makes very easy riding. I would like to know how many people have stacked on a bike path over the age of 16. But then if somebody was riding on the road, and smashes into a power pole, or even a parked car, thats when you need a helmet (not saying it will help a lot). But if the law is retracted, it would only have to be on bike paths, but i guess if they are council bike paths doesnt that leave the council liable? i think the idea for over 18s have the choice is a good idea, becaue at that age your able to make your own decisions about drinking and smoking etc, and these could affect your health, so why not be able to decide on wearing a helmet? and to add to the whole "how much differense does a helmet make" debate, it does. I know a guy that the police ask to analyse a bike crash, to determine who is at fault and what happened, and he said that a helmet is often the diference between a injured person sueing a driver, and a dead guys family that whats to know what happened
