Mercedes lists their limitations and sells their system as with those limitation. Musk markets FSD as "full self driving" which it is not. He markets autopilot similarly, and it is not.

Mercedes' fine print match their marketing. Tesla's fine print does not match the public marketing statements made by their CEO. The latter is the problem.

I run a company that makes and sells computer control systems. It is no small thing that Musk says things frequently and over many years that do not match with what his company sells and delivers. The word for that is "fraud."
