Recently, within the past few weeks, I've seen TONS of cars with a barcode sticker on their windows. What the fuck is this? Fast cars, slow cars, expensive/cheap, etc etc etc. Every car and any car. Am I missing something? Is there some car check out place or what? It's not a small sticker either, it's fairly big. Anyone have ANY idea what this is? The best logical thing I could think of was that a small dealership was using it to keep track of their inventory and the customer's never peeled them off?
