The NHTSA thinks eating while driving is one of the most dangerous things you can do behind the wheel. An insurance company study resulted in this list of the 10 most dangerous foods to eat while driving (we always thought it was a Taco Bell bean burrito when there are passengers in the car, but, maybe that fits in the category of "air pollution"):
1. Coffee.
2. Hot soup.
3. Tacos.
4. Chili dogs.
5. Hamburgers.
6. Ribs and wings.
7. Fried chicken.
8. Jelly donuts.
9. Soda.
10. Chocolate.
