Some of the information being recently posted on this thread is not of a high quality. Yes, some of the information may be from Tesla's own website, but this website often contains information that is years old (see the issues concerning Tesla's advertising of Premium Connectivity). Years ago it was stated that Tesla was moving from Radar to vision as a primary sensor (I think it was after the first fatality), with Radar and ultrasonics simply confirming to the computer that its predictions were correct. It has been long known that Tesla plans to move to a fully vision based system, with Radar confirming/assisting in some circumstances. Therefore, the ultimate range of cameras will have more to do with pixels and software perception limitations than whether they are placed on a roof and called 360 degree vision.
Research is non-linear and difficult to extrapolate. Elon has optimistic timelines. However, when you are venturing into the unknown, you can't know what is going to happen. It is impossible. You can only guess. Am I disappointed in the rate of advancement of FSD (something I paid for years ago)? Yes, I am. However, some of the critiques on this page indicate a very poor understanding of the groundbreaking challenges.
