I'm guessing the "cues" mentioned are triggering the app to show up on the lock screen. Without it you'd be forced to sift through your apps every time you back up. I don't think there's any other way to know for sure you're in a car and will be backing up soon. Ideally you'd want your backup camera on before the accelerometer knows you're backing up.
