Although companies have been making ads that prey on their customer's fears since the first day of marketing, these ads have never been as audacious as the banned Smart ad. This ad encourages you to buy a Smart because it has no backseat.
Normally, having no backseat would be a detrimental feature to a car. The banned Smart ad shows that having a backseat is actually extremely detrimental to your health. Scenes from famous movies of people being murdered and kidnapped by villains from the backseat are featured, making it appear to be a scary thing to own a sedan with a backseat.
