I was behind a black minivan with a self-congratulatory, self-righteous, pretentious sticker on the back "I'm sorry for driving the speed limit". Instead of being able to drive 45 in a 35 MPH zone like I like to, I was stuck behind them as they were driving 38 in a 35 MPH zone. Maybe they should change their condescending sticker to say "I'm sorry I break the law differently than you break the law."
