Some cyclists are simply too dangerous. This morning I was riding my bike on the nearby trail. I was passing a runner on her left when this cyclist came like a demon and yelled "on your let". So, he basically wanted to pass me on my left, at the same instance that I am passing a runner on her left. Taking into account how narrow this section of the trail was, I would say this guy's brain power is limited. To make things worse, I just couldn't do anything in that second of passing the other person, so he decided to pass on my right (having indicated a left pass) between me and the jogger. He was easily going faster than 25 mph. That was a close call for all three of us. So, even cycling on a non-trafficked trail could be hazardous
