Lol, I have a "you are a jackwagon driver if" list on my phone. My number 1 issue is people who don't use blinkers. That is just pure laziness. Manufacturers put them on vehicles for a reason, but I guess everyone is in the profession of mind-reading these days. The obvious one is left lane dwellers, but I'm always a fan of the people who sit in the right lane as people merge onto the interstate, while the middle lane is completely open. This just shows people are unaware, no courtesy, and it seems like they are scared to drive at all. My favorite are the people who tailgate to no end so closely when there are 5 vehicles (in the left lane) and you can't go any faster, so they proceed to weave in and out of the 3 lanes, only to exit a few miles down the road. I then pass them as they exit with a face palm.
