Music can help save lives.

In Brazil, traffic takes over 40 thousand lives each year. The majority of these accidents is caused by speedding. To fight this dangerous habit that drivers have, Dentsu and Arteris, took advantage of another habit of those who drive: listening to music.

Introducing the Speed-O-Track. An app that uses the music from Spotify and the data from Google Maps to warn drivers. When the driver is over the speed limit, the song being played speeds up and only returns to the normal rhythm when the car is once more, within the speed limit. Now music can save lives.
