Why would it be? The OBD-II port is inside the car, and police would presumably not be able to use it without a legitimate reason to search the car. I could see vehicle data being an invaluable tool in determining fault in car accidents or even providing the necessary clues to someone&#x27;s life to figure out who murdered them.<p>Since it&#x27;s offline and in person, it doesn&#x27;t lend itself to anomaly detection or other scary mass surveillance scenarios. But it would be irresponsible for a criminal investigator <i>not</i> to gather all available evidence. I want police to stop trawling for possible lawbreakers, harassing people for driving while black, etc. and give investigations of actual crimes the resources they need. This tool empowers investigators. This is what real police work looks like.
