I always do, and I never fail to get fucked over by the other assclowns on the road. I can get over it in my pick up, but when I'm on my bike, or in a tractor trailer, it tends to piss me off more. One day it was done to me on my bike, and seeing as the other person and myself were going to the same place, I casually mentioned, "I guess that model doesn't come with turn signals". I got a dirty look. I wish she would have said something, so I could have called her a stupid cunt.
