the common sense rule on streets, roads, car racing circuits and ski slopes is it's the overtakers responsibility to ensure safety. all those other path users are not as liable as the person that hits them.One of the main rules of health and safety is that 'one must take reasonable care of your own health and safety and that of others who may be affected by what you do or not do.' Pedestrians putting themselves in danger are just as liable. Where are the leaflets aimed at educating the joggers, the pet walkers and their total disregard of safety of their pets on absurdly long leashes, the parents who don't keep an eye on their toddlers assuming the area is safe because it's away from motorised vehicles? The river police should also target irresponsible pedestrians.
