Do they still show the gross movies of car crashes?!
At my daughters' high school the police come by each fall and set up a little go-kart course and the kids try to navigate the course while texting, to show them how difficult it is. It's a good idea, but not terribly effective because the kids end up having a blast.
When I was a teen we never saw a movie, but a completely wrecked vehicle would always make the rounds and sit on the grounds of the front of the local skills to visually communicate the devastation drinking and driving could cause.
