You're either being facetious or ignorant. The marketing name of a model, especially nonsensical terms such as "blue motion", are clearly recognized by anyone as being pure marketing terms chosen for aesthetic reasons.
By contrast, car features generally have non-misleading names - "anti-lock breaking system", "cruise [speed] control" etc. "Full self driving" goes beyond the pail any way you look at it. It is a very explicit name: it means very specifically that a car can drive itself, with no human intervention whatsoever. Even more, Elon Musk, the CEO of the company, has repeatedly claimed to buyers that FSD will allow the cars to work as robo-taxis that can be allowed to work for their owners while their owners are otherwise occupied. This again very explicitly says that FSD doesn't require any human intervention whatsoever.
The fact that, after realizing that it obviously is nowhere near close to such a thing*, they started putting in warning that Full Self Driving is in fact not full self driving in any way shouldn't excuse them. They have obviously repeatedly lied and misled buying customers, and the name has to be changed.
*(and won't be in the next 50 years, most likely, until we actually start seeing AGI or something)
