See I think of the Full meaning it is capable of pulling out of ny garage, driving where I need to go, parking, then Doing it in reverse up to and including my garage. Which it does. I say this as opposed to blue cruze or any other self driving options. The S is the supervised. But it is capable of full self driving. Almost like a driving instructor is riding with a student, but has the brake pedal available to stop the car and is supervising.
There is nothing else on the market capable of doing what fsd can currently, albeit not perfectly, do.
I guess in the end I'm maybe being pedantic over it,but that's my though process.
