On a pet I don't mind.
On myself - not even over my dead body.
We are allowing our government to track us more and more everyday. On star is one of those prequels to what is comming. So now they can start, stop your car, lock your doors, monitor speed, impact and aspects of your driving. Look forward to insurance companies using this info to not pay out if you wrecked and were going 1mile over speed limit. Eaves dropping through the on star mic to collect information and/or evidence to activity in vehicles. Tom Toms, garmens and other GPS systems as well as cell phones can all be used to track you and your vehicle. Next your navigational system will just upload a report of your speed to the police and you will get a ticket in the mail. Think of it this way, if you can think of it, they are already doing it or in process of implementing it.
