When I first saw this campaign from Italian carmaker FIAT I was convinced that we had a contender for our Car Industry Strikes Back series. Then I realised it was a campaign for drinking and driving.

The text, in Portugese, reads. "Now you see it. Now you don't".

Simple and effective marketing.

Here's the film version of it. And more info about the campaign is available here, in Portugese.

Thanks to Eduardo for the link.
