Traffic Circle

After being trapped in a traffic circle with a clueless mini van driver, I have come to the conclusion we need to re-evaluate the licensing process. Only people who receive an "A" on the driver's exam would be allowed to drive a large vehicle, "B" would relegate you to a mid size car, "C" would place you in the compact category, "D" downgrades you to a bicycle and "F" well as they say "Feet Don't Fail Me Now".
