Please try to widen your focus beyond that one single act. NHTSA and other bodies have a general responsibility to ensure safety of vehicles on the road, including preemptive as well as retrospective actions. That's what I was referring to. I see from other comments that you've been made aware (especially by Syonyk) of the relevant standards and procedures. Ignoring them now seems like just a way to pick a fight with someone who probably agrees with you on the general principle.

That's an unnecessarily and counter-productively pejorative phrasing (and it's not particularly clever wordplay either BTW). We as citizens do indeed have a right (if not a duty) to express opinions about the regulations imposed by our government agencies. The fact that Tesla's update affecting safety could go out with no oversight is simply wrong. Raising that awareness - not just within NHTSA via a safety complaint - is part of making the wrong right.
