In a refreshing change from the one-sided privacy intrusions of the modern world, the Chevy Volt hybrid's OnStar system is being used by its owners to create a website to share and access data about their driving, in a manner they control and benefit from:
Rosack initially wanted to do more with his own driving data than just view it on his phone. So he built what eventually became Volt Stats to capture this data, then started sharing it with other Volt owners. There was just one small problem: Volt Stats relied on Rosack's reverse engineering of an interface for OnStar's RemoteLink mobile application (iOS and Android). When OnStar moved to shut down the Web services interface Rosack had plugged into in mid-October, Volt Stats arrived at a screeching halt.
