Now that your hands are free, what can you do with them?

My first week in Los Angeles five years ago, I was simmering on the I-10, stopping and rolling between 0-40 mph, when I looked over and saw a young woman painting her nails. OK, not recommended, but not heinous, right? Except that she was painting her toenails. She had her foot up on the dash and she was dabbing red lacquer on her toes, very carefully, one by one, while steering with her knee. It was then I knew I had landed far, far from Kansas.
