I too think the single screen is great for simplicity and making the cost of features I don't care about (many) low because they can just be buried in a sub-menu.

Tesla UI has always seemed pretty terrible to me though. Their use of space, and insistence that you need to see a photo realistic picture of the car you are driving that takes up a massive amount of real estate is crazy to me.

On the other hand, I find a lot of car companies struggle with UI once screens come into play.
