Fun fact - if you buy the car new, you may have the "option" of being presented with these choices before purchase. And you can actually refuse! The dealer will be confused as hell, but they are hell-bent on selling a new car, and will actually void it if possible. I know because I've done it. You don't want the weird spyware (OnStar, Carnet, etcetera)? After agreeing to buy the car, refuse to accept the terms (they legally require your signature for this), and they'll find a way to get around it. If they refuse then go buy a different car, because fuck those guys.

Obviously this will vary by manufacturer and feature, and it's getting harder as time goes on to remove this shit from your vehicle.
