That's the perfect sticker for the rear bumper on @charley's Tow Mater jammies! Mater is great at driving backwards, because he doesn't need to know where he's going as long as he knows where he's been.
I need that as a bumper sticker also! A perfect add-on to the previous Mopar suggestion! Next to the cartoon depiction, I would add: "I don't use GPS. I don't need to know where I'm going as long as I remember where I've been". I will get Insider to color the letters.
