The app plays a Spotify playlist chosen by parents to embarrass young drivers when they speed or text

Toyota has launched an app intended to goad teen drivers into using safe practices behind the wheel by threatening to play their parents' music if they reach for their phones or break the speed limit while driving.

The app, which was created by Saatchi & Saatchi London, is called Safe and Sound. It also blocks teens from viewing social media posts and answering incoming calls when they are traveling faster than nine miles per hour. If they grab their phone or drive too fast, the app automatically plays a Spotify playlist chosen by their parents.

Safe and Sound uses Google Maps API technology to determine when drivers are speeding. When a teen driver slows to a safe speed or stops interacting with their cell phone, the parents' music turns off and their own music can resume. The app is available only for Android phones.
