Privacy advocates will roll on the floor and scream like angry toddlers, but really, in 2022 every car should have remote tracking and disabling features shared between the registered driver and law enforcement. If a leasing company can remotely disable a vehicle, why can't I or the police acting on my behalf?
Right, I'm going to install a tracking device on my car and give the login password to the local police department. I'll just say "If I report my car stolen, please log in with this password and track it's whereabouts, and at your convenience go retrieve it and impound it until I can reclaim it". I'm sure they'll be glad to write all that down, and file it in a file cabinet marked "crazies".
No, you do what the car rental companies do. You sign up for a monitoring service, like OnStar, who will contact the police for you and give them the relevant information.
