The U.K. this week launched its first-ever national ad campaign to stop people from driving on drugs. The centerpiece is the TV spot above, in which a pack of friends cruise around town, high on something or other, with their freaky big eyes evidently a dead giveaway for police. The ad's certainly memorable, even if it's exaggerated. (Only some drugs cause wildly dilated pupils, and nothing as cartoony as this, and the police would notice them only after a traffic stop, not from a distance.) It's also noteworthy for what it doesn't include: the kind of horror and violence we've come to expect from British road-safety ads. For that, you'll have to head over to Wales, where a local police force has scared the crap out of people worldwide with its grisly "Don't text and drive" video below.
