An iconic scene: two young drivers - taunting and posing - a girl with a scarf - a drag race!

The sounds of roaring engines and a building sense of anticipation.

But once the flag is dropped, the drivers each launch a mobile app, and drive very safely.

The VO explains that young Allstate customers can race their friends to be the safest driver, and save money on car insurance.
