These days "professional" thieves aren't going to jack your car...they'll back up to the driveway and yank it onto a flat bed and drive away with it in one piece. They don't wanna mess around deactivating your anti-theft devices in your driveway and risk getting caught. They'll dismantle your car at a safer location.
