I absolutely detest Salmon and Ninjas whenever I'm cycling or driving!
They're all hazardous to everyone on the road. I once made a right-hand turn straight into the path of a salmoning cyclist. I was forced to hop upon the sidewalk into a bunch of pedestrians!
One dark night while on my way home, I was casually cycling at about 12 mph, with a flashing red tail light behind and a really bright headlight in front, when a Ninja streaked through his stop sign, just perpendicular to me and directly in my path. It was sheer luck that we didn't collide! I can't tell you how many times I had near misses with Ninjas while driving in San Francisco...
