Yeah, nobody would willingly buy this. I certainly wouldn't. Never mind the obvious perpetual privacy violation baked right in to a hairbrained scheme like this, but could you ever fully trust it to work correctly and not ever randomly (or not-so-randomly) send people up for prosecution under false pretenses? I guarantee you the speed tattle system will be a black box, some dipshit legislator would pass a law making fucking with it or reverse engineering it a crime "because safety," and then any time the state wants to harass anyone they can just ping somebody's Ford to spit out a false speeding ticket (maybe even one that's egregious enough to count as a felony like 130 in a 25, or whatever). And how are you going to be equipped to argue against it? It's going to be your word against the computer and Ford's army of lawyers and experts plus the police, in a system that's already heavily stacked against the defendant.
This will probably only see any actual use being built into police cars and maybe commercial fleets, but not civilian vehicles.
