Like I've been saying here along with a few others, if Musk was really betting on this and believed that they are ready for this change, then the redesigned S and X would not include a radar. This isn't so much a proof of Tesla's conviction about their vision-only philosophy, but rather an experimentation on a large segment of their consumer base, born mostly out of supply chain issues and a desire to continue shipping vehicles to customers.
It's pretty clear that all the recent noise from Musk about the vision-only approach has been a planned PR move to mask the fact that they were going to have to gimp the M3 and MY, at least for the short-term, and potentially indefinitely just so they could continue selling their cars due to the parts shortage.
I have no issues with Tesla going down the vision-only path. But to me, this is transparently not a move made by Tesla in good-faith. If they were truly ready for this change they would have already proven to themselves that vision-only could handle everything just as well, if not better than the previous hybrid system. They would also then be prepared to seamlessly switch their software over to provide the exact same current feature-set rather than gimping it as they have at the moment.
