Personally, as someone who doesn't use Twitter, I recall no such thing, but it certainly didn't appear to happen in this video.
Should we be concerned that the driver didn't read the release notes, or concerend that the driver didn't understand them?
"a wide angle lens"? A lens judging distance based on motion probably wouldn't be good enough at all. AFAIK, there are multiple lenses and stereoscopic vision involved with the field of view that this pedestrian would have occupied. Keep in mind that FSD is, in fact, NOT human, and should, accordingly, be able to accurately and consistently account for any distortion that MIGHT exist in the stereoscopic view using math, which computers happen to be pretty good at.
"Buzzed the turn?" In my experience, you'd be hard-pressed to get FSD to do anything that might even have a remote possibility of triggering a skid outside of driving on ice, it's not even remotely aggressive when it comes to cornering, and using the accelerator in an attempt to override that will lead to a wider turn, even if it crosses double-yellows or goes off he shoulder.
Who is complaining? Unless it's people on Twitter, you are being overly dramatic. Prior to this post to which I'm replying, all discussion here since you posted the link to the video has involved why this happened or distinguished between fault and feature. I certainly haven't seen any complaint about the video post.
Frankly, your post with the tweet was reasonable, but in my opinion, your arguments about why other people should be as concerned as you claim to be are a bit out there.
