Oooooooooooohh. I get it now. You were over-analyzing this. I didn't catch that at first. I'm quite sure these stickers weren't meant to be left on forever. The point is to slap the sticker on and snap a pic of it and send it in to the website. When the owner of the car sees it and removes it, more than likely, he/she will be curious enough to look at the website and possibly see his/her car on it. Later, QD.
