Why is this suddenly an issue with hybrid vehicles? Bicycles have been around a lot longer, and are possibly more numerous in urban areas (where pedestrians also are more numerous), than hybrids. Though they certainly won't be as lethal as a car in a collision with a pedestrian, they can still injure seriously. How do blind pedestrians recognize an approaching bike? Why has there been no similar push for bicycles to make noise for the benefit of the blind?
Maybe the suggestion seen in another forum is in order, for both types of vehicles: clothespins and baseball cards.
