Self-driving features? Sorry, there are no some self driving features. You either have full self-driving or you don't. If you don't (which Tesla doesn't), how the hell can you call it self-driving?
Your comment appears to contradict itself. Using the term "full self-driving" implies that you'd recognize something short of that as "partial self-driving". Such a system would presumably have some, but not all the features of a "full self-driving" car.
In any case, it's quite easy to imagine a plausible meaning "some self-driving features": perhaps these features enable the car to drive itself [without oversight] in some, but not all situations (<i>e.g.</i> on highways, but not in cities).
