I can't believe some bike riders in seattle either (and I'm one - in the nicer months) Like a bunch of arrogant f$#@'s in a "pace line" I saw weaving through summer traffic on the Burke Gillman at 25mph rudely shouting "cear!" at everyone they came up on.
Another time some dude decided to clear his nasal passages as I was behind him (five or six feet), spraying me with snot. I was so pissed I almost kicked him of the road as I pulled up beside him to motion as if saying "what the f*#$@ man!" He gives me an irritated look and says "hey didn't know you were on my wheel"
Not to mention some of the things I've seen in traffic. I keep expecting to see a tragic accident one day, but, amazingly, it hasn't happened yet.
