There is a growing number of cases where the salesperson will activate OnStar (or a non-GM equivalent) without asking or telling the buyer about it. As far as I know, there is no (legal) way to deactivate OnStar or similar GPS trackers built into cars. Of course if you're driving in a city the proliferation of ALPRs is so pervasive that your movements are being tracked in real-time even if you're driving a 1958 Ford F-series truck.
