This is not correct. Elon never promised a 360 view like those that use parking cameras. Before the occupancy network even existed, he promised a vector space bird's eye view for FSD Beta which the engineers did make and release for FSD Beta. This was presented in various technical presentations about autopilot by Andrej. This was as opposed to the previous raster based road lines.
It was others that interpreted the bird's eye view (BEV) as 360 parking camera, when that was not what he meant.
Here's an article on how Tesla's vector space BEV worked (this was before the latest occupancy network):
