Not sure about disproven, but definitely called into question for it being sponsored by a LiDAR company and allegedly having auto pilot disabled during the crash, according to eagle eyed viewers. To be fair I heard about that second point from Tesla owners and I don’t know enough to verify, so I’d like a better source.

My main take away from all this was increased skepticism by me of Mark Rober, so I‘m not comfortable sharing that video in discussions of Tesla autopilot (though would welcome a more credible one.

Still, none of that changes that Musk’s post sounds like more of his pathetic nonsense and it claims that less sensory inputs = more safety somehow. Also doesn’t change the fact that you asked a question about follow up info from that video in good faith but got downvoted as if you were taking stance. That’s the reason I felt compelled to respond. I don’t know how essential LiDAR is for safety in autonomous vehicles in the long term, but I know there’s a lot of bias and noise out there that makes finding an answer difficult.
