Not too much to specifically take away yet, but appears that the degradation detection system did not function well. That is pretty egregious for FSD given a human won't be able to tell if FSD is confident or needs the human to intervene. I'd expect this to be a VERY important test case with high reliability of passing, but who knows.
Overall, yikes.
A reflection on a white truck makes it confident that it can move into that truck. I really have nothing else to say (happened to my friend).
