No onstar ,bluelink,Ford sync can all shut down via the 4G link that’s always active regardless of if the service is on it’s hardwired to the engine’s ECU so is the SOS button even when the service is off press that button it will connect you to EMS and cops by law. Cops don’t directly send the shutdown even in a chase they have dispatch contact the respective companies data center and send the stop command via the 4 G network it just kills the accelerator pedal the car coasts to a stop you don’t kill the engine or power steering and brakes fail.
NOt good in my books.
