Again, they added it back the same day. It was even mentioned on the reddit thread that reported it! The comments even mentioned they didn't see any change as the edit was so fast.
Yes, and it would have died there if that was it. But then NHTSA and CS and IIHS started dropping ratings, and it became a real news story, because at one level it's true that they don't have AEB if NHTSA won't put it on the NCAP ratings.
However, the real discussion here is if Tesla rushed vision only because of shortages. Some people say no, this was a well thought out long term plan, and isn't driven by supply chain or anything else. It's just Tesla's way to commit to HW before SW and have times where customers have no idea how long they will be without features while the SW catches up, but and we should just accept this, and wait a few months to see how it shakes out. No way Tesla has "doubled down" on vision only without great data that this will work out, and shows that Tesla is committed and in the lead on inexpensive, vision only autonomy.
Others take the totality of data (many edits to website on one day, removal only on 3/Y in NA, not S/X or other countries, no pre-discussion with NHTSA, reduction in features, confusion on if AEB/FCW is there (Even Elon had to "check with the AP engineers", removing blog posts, cars sitting in lots, end of quarter, Elon suddenly talking up vision only about 4 weeks before, etc) as evidence that this was rushed, and not planned, and is not being done because it's "better". Only a very immature company would behave and communicate this way if they knew this was coming. No one detail like the website edit is important, but the totality is really suspicious..
The second path is very problematic, as we've seen it before with Tesla, and it doesn't end up with a good customer experience nor indicate that they are as close to vision only as they keep saying, or that they have things more under control, which just means all other AP and FSD stuff is that far behind the dates they keep giving us, and this is the same old Tesla we've been seeing for 5+ years.
