Here's a short demo of the Pandora MINI BT V2's anti hijack in action, this golf also has warn away, shock, tilt, movement and motion sensors.
As soon as the Pandora proximity tag has been removed and the car door opened, this system begins a count down in order to let the owner know the tag or security code is needed. If neither have been picked up by the alarm the vehicle simply stalls at a low and safe speed.
