Twice now in the past week, cars that I am passing have decided to pull into my lane right when I am next to them so that I've had to slam on the brakes and blare the horn in order to keep them from hitting me. On numerous other occasions this week, cars have breezed through their stop signs without slowing just as I'm traveling through the intersection, suddenly pulled out in front of me from the curb with absolutely no warning (or space for a car), and unexpectedly cut me off as they did U-turns in the middle of the street. I have no idea how I have managed to keep our car in one piece.
