Presumably, Tesla knows which cars cameras took which photos, so pairing them up with the car owner wouldn't seem hard. Unless, that is, the owner takes seriously Tesla's claim that the cameras are there "to assist driving" and are “designed from the ground up to protect your privacy.”
Reuters's list of examples included a lot of faces. I don't suppose anyone at Tesla or elsewhere in Elmo's organization have access to facial recognition software. No?
