Not to put a damper on your day or steal your sunshine, but "talking on a cell phone" is around #10 (number ten) as a cause of traffic accidents, well behind changing the radio, eating, drinking (alcoholic AND non-alcoholic type), READING A NEWSPAPER (just for emphasis, can't believe people do that), and several other things. It's easier to notice such because of the phone to the head, but I assure you it's by no means anywhere near the worst offender.
