Mozilla: It’s Official: Cars Are the Worst Product Category We Have Ever Reviewed for Privacy

This car comes with a GPS and cell modem embedded. In case of an accident (no user interaction needed), the car will phone the emergency services, call for help, and share the current location of the vehicle. I can also press a button, and get in touch with the emergency services, using the car's phone (not mine). The car can also download and install firmware updates (I guess/home that just for the entertainment features), using it's own internet connection.

So, this car has both a GPS and an internet connection; it is entirely possible that it phones home regularly, and sends information about my whereabouts or my driving habits.
