The ones who feel the need to "prove" something to a rider lol. I was in the middle lane, at an acceptable speed, and some dude passes me on the right DESPITE there being a car in the right lane going slower than me. There isn't much space at all. But he passes me on the right and then gets in front of me. Caught a smell from behind and dude was definitely driving high. Gave him the insta-bird.
