The music you listen to can alter your driving styles. Softer music can make you a more cautious driver, while upbeat tunes make you more aggressive. A new app from VW will generate music in real time based on how you drive.

Designed to collect data while a smartphone is connected to a VW GTI's computer, it takes everything in to computation from speed to engine RPM, acceleration, G-forces and even GPS location into account to generate a unique soundtrack.

The app was developed with dance music group Underworld but isn't available to the public just yet. Volkswagen is using it for a competition where drivers can win the opportunity to 'compose' their own track on a special course.

Just know that it won't be a smash hit on radio anytime soon. Check it out below: [Volkswagen via Damn Geeky]
