Here's a pretty brilliant way to get people to stop texting and driving. Volkswagen played a new ad before the previews at a movie theater in Hong Kong recently. The first 10 seconds were of a car driving down a road, from the driver's point of view.
Then they sent a text message to everyone in the theater at the exact same time. And when people looked down to check their phone, the car CRASHED. Then a message about texting and driving popped up on the screen. It's probably staged, but still.
(Even if Volkswagen had everyone's phone number as part of a promotion, or could mass text everyone in the vicinity . . . in real life the crowd would react to the sound of everyone around them getting a text at the same time, right?)
(Search for "Volkswagen - Eyes on the Road." They get the text at :52.)
