Cars need gas to run. If you don't fill your gas tank up again before the little icon signals that it is empty, the Explorer will not 'go'.
And you will be stuck on the side of a busy highway out in the middle of nowhere on your way to a play date, with your hazard lights flashing (after you figure out where they are located), trying to get a bar on your cell phone because you are in a dead zone and it's gonna take a few calls to get ahold of your husband to ask you come rescue you, telling 2 strangers and 1 policeman that Hubby will be there any minute, thanks for stopping and checking on me and the 2 children in the backseat asking lots of questions and Bud calling the officer a Super-Guy, like he is Spider Man, through a rolled down window all while a train rumbles past right next to where you are parked. Or should I say stalled.
So, Sonya, if you can do me this little favor and manage to stop at one of those gas stations that you see all the time while driving here and there and use one of their pumps and fill your gas tank when seeing it get below a quarter of a tank, all this won't happen again.
