The easiest way to know if this is legit is to ask yourself if Pepsi, NASCAR, and Jeff Gordon would knowingly expose themselves to huge liability suits. All three have deep pockets and an acute awareness of public relations. The commercials are entertaining and I figure Gordon gets a kick out of making them. Looks like he drove for this one, the original was not him on the wheel.
Careful, and I mean careful, target selection, prompt insertion onto a closed course, and the cooperation and assistance of the dude's employers. Oh, and a few grand of 'hush' money as part of having the video actually released.
Plus, well, they might of had him sign a contract saying that they were going to do something, just not exactly what.
Would be interesting if he turned out to be carrying. Quick way to end the whole thing.
