Really, report this to to NHTSA "if that's your jam"?
I'm the former Executive Director of NHTSA, and the agency absolutely wants to hear from vehicle owners if they think they have a safety problem with their vehicle. The agency can't make a decision as to whether a vehicle has a safety-related defect if they're totally unaware of a possible vehicle safety problem in the first place.
Nobody on this forum should be discouraging drivers from reporting an issue to NHTSA if that person has a safety concern about their vehicle.
And, assuming you're right that 2.8.7 is "a bad (and cancelled) update," Lucid needs to do some serious shaking up of their software team. As 2.8.4 was apparently also cancelled, this means two of the last three Air updates have not worked without introducing major issues. And both of these were significant updates that required almost two hours of installation time each. So, even though they weren't advertised as being "feature" updates, they still were time consuming for vehicle owners and, despite that, appear to be problem-filled.
