cold fjord writes "The Detroit News reports, 'A government report finds that major automakers are keeping information about where drivers have been — collected from onboard navigation systems — for varying lengths of time. Owners of those cars can't demand that the information be destroyed. And, says the U.S. senator requesting the investigation, that raises questions about driver privacy. The Government Accountability Office in a report released Monday found major automakers have differing policies about how much data they collect and how long they keep it. Automakers collect location data in order to provide drivers with real-time traffic information, to help find the nearest gas station or restaurant, and to provide emergency roadside assistance and stolen vehicle tracking. But, the report found, "If companies retained data, they did not allow consumers to request that their data be deleted, which is a recommended practice."'"
