I'm not sure what you mean, precisely. The grand goal IS complete autonomous function, but it's wise to approach this with caution. Legal and moral grey area abound, new technology brings new technophobia, definite "completeness" would require rigorous proof and we're JUST getting autonomous vehicles into the wild.
But the kicker is that if you actually care about the safety of the public, then you have to care about whether or not the public will adopt the new technology that makes them safer-- and to do that you have to introduce it slowly and respond to criticism.
Other companies are being even more cautious; Ford isn't putting autonomy on the road until 2021.
In the meanwhile Tesla can sell products as Level 2, and perhaps should do so until roads are as safe as commercial aircraft.
