Why do *I* have to figure it out -- are you too lazy to find an answer to
your own question?

READ the article you posted.  Or, any of the other articles about folks
being "profiled" for higher car insurance premiums because their
driving habits were made available to LexisNexis (by GM).

Ask yourself how GM got that information.

Ask yourself how your car "knows" what the current traffic conditions
are like.  Do you think they have a special set of satellites flying
to visually track traffic flow?  or,m do you think the cars already
on the road -- knowing exactly WHERE they are and their current
speed -- are collaborating with <someone> to produce a live map of
traffic conditions (that can then be sold -- as a service -- to
those verysame folks as subscribers)

Buy a Workshop Manual and dig through the vague module descriptions
moving backwards from the antennae and see what you find.
REMOVE those module(s) and see if your car keeps tattling.

Or, *running*!
