"If you borrow a gun from me, and I don't know that you did, and you don't or won't tell me that you did... oh well. shrug" becomes your expectation of what should happen next.
"Oh sorry, you weren't driving your vehicle, and you have no idea who was, when it was involved in that accident. But you know it wasn't stolen. Guess there's nothing more we can do here, have a nice day."
You're arguing that because a gun or car is dangerous, ownership implies liability. There are few things which can be possessed which cannot be dangerous in the wrong hands, and a car is not actually intended for the purpose of murder, so one should probably not judge it by that standard. However, I did explicitly consider the case of an inherently dangerous object, so I cannot have left out that part as you suggest. I am really not sure what part of this concept you could possibly have an objection to. You know we're talking about a car, right, not a hydrogen bomb? Surely you can do better than that?
