You're right -- most people have no idea, or don't care, that a system like On-Star is actually "Big Brother." If you have it and use it, anyone can know where your vehicle is located within 10 meters any time of the day or night.
Many cell phones also contain a GPS receiver with the same capability. You can do one of three things: either set the GPS receiver to activate only after you dial 911; or, completely disable it; or, do either one of these suggestions AND completely turn off your phone except when making a call.
