That's Elon's conundrum, everyone has a different definition of what "premium" is based on their personal wants and desires. Elon's trying to make a car that is relatively affordable, relatively profitable, and relatively "premium." I don't fault what is on your list but those items/features are not on my list. For example, I define seat memory profile as "premium" and the model 3 has that. I define a high tech ventilation system as "premium" and model 3 has a feature that no one else has. I define an all glass roof as "premium" and the model 3 has that. I define a FSD capability interface as "premium" and model 3 has something no one else has. I don't expect anyone to agree with my list; I am personal and unique.
I guess Elon took the suggestion from Ricky Nelson in the Garden Party lyrics, "You see, ya can't please everyone, so ya got to please yourself."
Wife an I are looking for a car for her. Base requirement is for as nice/ adjustable seat for the passenger as the driver (it will also be the car we take when both of us go somewhere). Amazing how few like that there are, Tesla being one that does.
So, yah, one person's premium is another's minimum (same deal with head room).
