How Am I Driving?

You ever see those commercial vehicles with the How Am I Driving stickers on the back? I tried to the other day to take a picture of one of those stickers with my iPhone so I could call it later and complain, but the guy was driving so erratically...this is all I could get...after he cut me off.

So there it is. A graphical depiction of how he was driving. And I can't call because I can't read the number. Sure I could have dialed the phone instead of taking pictures, but then I'd have nothing to write about. Has anyone ever called one of those numbers to complain? And even better...anyone ever call with a compliment? "Your driver was so courteous...he stopped at every crosswalk and got out to help an old lady cross the street".
