Drivers Turrets

My roommate and I were running errands for her on Saturday. Since her fiancee took her SUV to Arizona for the weekend and left his little compact, we were using my van to haul stuff from his apartment to their married house (remember that one time that I was nice? This is time number two). As it was my van we were driving I was doing the driving. Turns out I talk to people when I drive. Sometimes I say nice things. Sometimes the things I say are less than nice. My roommate has decided that I have "Driver's Turrets". Well, we've identified the problem. Now she wants to fix it. Tragically, I don't think it's that much of an issue for me.
