NYT:
"If you drive a car made by General Motors and it has an internet connection, your car’s movements and exact location are being collected and shared anonymously with a data broker. This practice, disclosed in a letter sent by two Democratic senators to the FTC on Friday, is yet another way in which automakers are tracking drivers, often without their knowledge."
@GottaLaff "anonymously" could easily be a negligible concept here. Generally, not more than one person travels from one house to one work location regularly, and any extra visits could be tied to that person.
