Eating behind the wheel on a regular basis significantly raises your risk of getting sick. That’s according to microbiologist Dr. Anthony Hilton from Aston University. He says the average family car is teeming with the germs that cause food poisoning. And the germiest places are the steering wheel, gearshift, and door handles. So, Dr. Hilton recommends cleaning everything in the car that anyone could have touched with a disinfecting wipe at least once a week.
