Sure. But if we have enough surveillance cameras, we can just trace the full path of the car from the moment of theft to now. I'm reminded of Gorgon Stare [1]. Stolen cars suck. But how about murders? I'm sure all of the people who've had loved ones murdered in, say, South Chicago, might have a more positive opinion of such a system. Especially since it wouldn't have to rely on witnesses who are cowed by the threat of reprisal and anti-snitch culture.
