Extend the Story - Add a Room

You find one vehicle. It's run down, and most likely won't work. But you look inside, and there are keys hanging in the ignition. You think to yourself, well, I can just start it up, and take off looking for a payphone or a motel. You try the door, and it won't seem to open. Which seems peculiar to you, so you just break the window, and reach in, and the door is unlocked, it's just jammed. So you climb through the window. You turn the key in the ignition, and you hear a low rumble, and smell some gas, but you know it's not just any kind of gas... You think that's not normal... You...

You try & jump out the window.
