How Well Do You Know Your Car?

When I started my car this morning I heard the DING. I was very low on gas.

I hate that DING.

But, I know my car so well, I know how much gas is ACTUALLY in the tank. Do you know YOUR car this well?

If you look at the picture for this article you will see that my car tells me how many miles I have. HOWEVER, I know there are exactly 2 miles to the highway and almost 7 to the gas station that's open at 4:30. Would I have enough to make it?

Of course I did. I know my car THAT well.

Are there things about your car that only YOU know?
