Few people would argue that bicycles and people on foot are not a dangerous mix – except those cyclists who apparently believe city sidewalks intended for pedestrians also belong to them. And not without reason; cyclists never finish first in collisions with vehicles and are justifiably fearful of a fast-moving truck, inches from their handlebars. They are run down, maimed and killed with frightening efficiency. It might come as a surprise to cyclists – accustomed to the righteous role of victim in all violent encounters with traffic – that when a bike blows past a pedestrian from behind, so close the breeze from their passing can be felt, it is no less intimidating than their own close calls with bigger, faster vehicles.
