I'm sorry, what? No one thinks about what data is being sent back to the manufacturer when buying a car. Now I need to know what my car know and what is being transmitted back. It would be nice if I could turn off this functionality.
Well, at least one does. Me. The risk of that is the primary thing that is in my mind, over literally every other aspect of the car.
I also wouldn't trust that any controls to not send data would actually stop all data from being sent.
Chevrolet has had OnStar since 1996, and has sold data related to it for probably just as long -- this isn't some new phenomenon.
I remember these same arguments echoed back then -- but at least it was a unique happening at the time.
