Only drive cars made before Onstar and similar systems were added in the early 90s. They have been tracking you for a long time. But even then you need a license plate, which is constantly collected in most urban areas, stored and sold. It’s really impossible to travel anywhere even if you have no phone giving away your location. Flock and all the surveillance systems also tie into the license plate data. Cars began having cell connections and other ways to broadcast data after the onstar type systems were added. Now it’s a whole other world with the amount of data cars like Tesla can collect. /OldManRant
