I tried Googling it and actually found what appeared to be a site for the manufacturer. However, when I get to the page linked to a "Get your Zero Per Gallon decal here," I get a notice reading "Site Suspended."

Maybe so many drivers were offended by this that they all got together and formed a coalition to stop it.

I think it's a cool idea, even though anybody with too much time on their hands can poke a million holes in it. My bike is full of tourist decals. I'd like to add one of these to the mix.
