If you're a driver who puts a premium on privacy -- you might not like the changes OnStar is making.
The General Motors communication service can start selling data collected from cars in December.
The device tracks speed, seat belt usage, odometer readings and how frequently you fill up your tank.
Under the new policy - OnStar could sell that information to credit card processors, law enforcement officials and others.
OnStar users were alerted of the policy change through an email.
