Beware of Idiots

What is it with Bay Street North?  Several days ago I watched in shock as someone drove a full-sized scooter pas me on the same sidewalk where I was hit by a cyclist.  He must have been going at least 40 km/h.  Apparently he decided that since he wanted to travel in the opposite direction of the one-way traffic that he'd just use the sidewalk, instead.  Not just an idiot, but a dangerous one.
