I agree that Tesla has done a lot to push us towards a more sustainable future with cars, and unfortunately I have to give Musk some credit for that also. The thing is, I don't think you can separate Musk and Tesla like you are trying to.
Without Musk there really isn't a Tesla. Even now they are very tied to him and his way of thinking. Nobody but Musk would ask someone to design the Cyber truck, and nobody but Musk would even call it that, or name the other vehicles so they spell S3XY, or release beta driver assist /self driving software to the public.
