you know your'e a hypermiler when you:
feel guilty when you roll up to a stop light and your still doing 15 mph and if you would have coasted longer you could have rolled to a stop.
When the only reason you have a pen in the car is to write down your mileage on your gas receipt when you fill up.
When you dread "running errands" as it's more city driving than you'd like on this tank.
When you, off the top of your head, no matter the situation, can tell someone how much gas you have left in your car and how many miles you have on that used gas.
