I'm not concerned about COPS extracting data from my car, I'm MUCH more concerned about car's OEM extracting data regularly from remote from "my" car, who is mine just formally being connected to it's OEM and who knows what others.

This is a FAR BIGGER threat even in national security terms because an unpatched vulnerability might allow acting on ALL cars in a nation, for instance blocking them in some crucial intersections paralyzing the entire traffic, or push them to consume too much all at once (EVs/plug-in hybrid) from the grid to make mass blackouts and so on.
