You're extrapolating from a condition that fits your view (tracking 1 vehicle). The point that I and others are making is that being able to cross-reference VIN and IP address will lead to the ability for various actors to be able to track massive numbers of vehicles. Some of those folks will also have access to the VIN database (whether they are state-sponsored, crackers, or "other") which leads to a whole new level of privacy violation. | If I can derive the VIN from the prefix, I agree that it helps | identify the vehicle, but not really. So if I know the VIN number of the vehicle I'm interested in, all I have to do is get on the network and figure out where it's originating its traffic from, and now I can dramatically narrow down its location, if not pinpoint it with a high degree of accuracy. I've run out of adjectives to describe how bad of an idea this is.

I have no idea what this is supposed to mean.
