Have you ever purchased a used car with bumper stickers that you dont like? Or have grown out of the bumber stickers on your current vehicle? They're a hassle to scrub off. Well how about a magnetic bumper sticker that comes off whenever you want, without the agony of scrubbing for hours.

Reward: Not having to spend hours taking off bumper stickers.

I would imagine they would get stolen right? i mean if you can just peel them off.......
