Hygiene while driving?

Not long after I had submitted an article on grooming in public, I witnessed a surprising scene. I was stopped at a traffic light and watched a driver doing something left for the movies. He was brushing his teeth, yes, brushing his teeth while driving.

We all know what brushing entails, and I was left questioning how he would complete the process. Is that what the second cup holder is for? Not a good thought. Five out of five dentists agree: practicing good hygiene while driving is not a good idea.
