I was very nearly struck by a bicyclist riding on the sidewalk when I was walking out the door of an office building with heavy foot traffic. I would have been really, really mad if he had run into me. Firstly, he shouldn’t have been riding on the sidewalk. Secondly, he shouldn’t have been going that fast considering that he was already riding in a place reserved for pedestrian traffic. And thirdly, he shouldn’t have been so close to the door. (Which was probably unavoidable since the sidewalk was so narrow.) As it was, I could barely jump back out of the way. A less nimble person would have definitely been run into. Some people are total jerks.
