Let your audience's brain fill in the missing pieces

Highly graphic and gruesome ads that should stop you from smoking or driving dangerously are not only not pleasant to look at, but also often fail to achieve their objective (according to books like "Influence").
This U.K. "wear your seat belt" ad shows that you can communicate these messages in a different way. I like the way it triggers the brain to fill in the missing pieces in an emotional way. (Books such as "Brain Rules" show that your mind is very good at this).
Watch the full 90 seconds of this ad, it is very powerful.
