Driving reveals true Personality

A person carries two personalities — one that he really is and the other that he wishes to show in society. In face-to-face transactions, he behaves the way society demands in order to protect his reputation. However, in a car, he becomes faceless — as if wearing a mask. Then, inhibitions are dropped and the real nature manifests itself in driving. We can easily spot these varying human natures in form of cars on the road — impatient, short-tempered, ill-mannered and bullying cars in contrast to gentle, well-mannered and courteous cars.

I wonder how one would drive, if his/her picture is displayed on the outside.
