We think Nissan has found its new spokesman for the all-electric Leaf. A microbiologist at the University of Arizona known as "Dr. Germ" says he's identified gas pumps as the biggest biohazard in modern society.

According to The Los Angeles Times, the results of the good doctor's research show 71 percent of gas pump handles are "'highly contaminated' with the kinds of germs most associated with a high risk of illness." Other cesspools we encounter on an everyday basis include public mailboxes, ATM machines and escalators.

So what should the budding Howard Hughes do when faced with such information? Well, before you try to avoid germ-infested gas pumps by buying an electric vehicle, know this: The study also found 40 percent of parking meters to be similarly infested.
