There is so much screen real-estate, Tesla has eliminated most of the painful nested menus you find on other cars with smaller screens.
That says it all. The big screen is NOT a distraction since you avoid multiple dialogs that you have to learn with the small screens. Instead, tesla has most controls on the wheel (pretty normal), and then there is a top bar on the screen in which you can move to a couple of different mappings. Issue solved.
The fact is, that all cars require some amount of learning where buttons are. With Tesla, they are located in 2 easy spots: the wheel and a very large screen.
