My parents came to visit and my father couldn't fit in our Honda Civic. His girth makes it necessary for him to drive a behemoth in order to be comfortable. This got me thinking: How many barrels of oil do you think the U.S. would save if we cut our obesity rate in half? I can think of a half dozen ways that being thinner would consume less oil. I'm especially curious to know if carrying around heavier people affects the average car's fuel economy in any meaningful way.
