I think the one thing that really ticks me off is when someone is tailgating me....
Cutting me off and then driving slow in front of me. WHY DID YOU CUT ME OFF? If you're gonna Cut Me Off at least keep driving fast.
II. People tailgating me on the slow lane and honking. That's how you get the bird.
III. Seeing people texting. Ya have any idea on the stats on how that's caused more accidents than D.U.I.'s now.
