What do you do while driving?

So I'm driving to work today and Jamie is following me. I know this simply because of her vanity plates. Anyway, I notice that both of Jamie's hands are near her mouth. I think she must be eating a breakfast sandwich with both hands. No, that would be silly. Of course! The only logical explanation is that she's flossing her teeth. Yes, this woman was flossing her teeth while driving. So you know she was driving with her knee. Texting, eating, talking on the phone, disciplining your children, putting on make-up, doing your hair. . . but flossing? That's a new one.
