Running on Empty

Everyone knows what the little icon in this picture is, right? We are all familiar with the gas light. It comes on when you are running low on gas. Most car manufacturers know human nature and give you the courtesy of a few gallons left when you hit this point. So, I have a burning question. How is it possible, given the warning, to run out of gas? I am happy to say, I have never run out of gas. The closest I came was literally coasting into the gas station on fumes when I was lost and couldn't find a gas station AND I didn't even have a gas light in that car. My husband, however, has run out of gas SEVERAL times. His friends have also run out of gas. I can't recall any of my female friends telling me they have run out. They very well could have and were just too embarrassed to talk about it, but I don't know. I have this theory that the running out of gas gene resides on the Y chromosome and I'd like a little help in my "research". Take a second and answer my poll. Don't be embarrassed if you've done it, the poll is anonymous. I will only make fun of you in my head.
