I disagree with your assessment of the one screen driving experience. First and foremost the use of the screen is incidental to driving. Just the normal eye travel one has when checking the mirrors is more than sufficient to pick up your speed and outside of that the glance time is insignificant. If you really want to make this fun, you don't even need to know as you can use traffic aware cruise control, a feature many cars have, to set and forget your speed on any road. I have two issues with the UI/Human interface that Telsa has followed. First, their automatic wiper solution is dreadful and while you can instant a wipe action by pressing the button on the end of the stalk I believe the variable rate should be available on the stalk. The second is that I think the steering wheel would be better served with buttons dedicated to cell phone use, namely accept, ignore, mute, and hangup. However it should be noted the cars voice controls respond very well and you can easily change the temperature should you want that way, there are a lot of settings easily changed by voice but Tesla does not alert you to them. The best way to grade their UI though is that I can muscle memory activate many features including one level down options. Of course you can just let the car drive and play with the screen all you want, something I have done to prove a point but the simple fact is... I rarely if ever, as in nearly never, need to access anything through the screen as its all set and forget. Now I get into other cars and think, damn this has enough buttons and screens to be an airliner. It won't be but a generation before we look back and wonder how anyone though six gauges, forty buttons, and three or more levers, were ease of operation, Not all cars will be as simple as a Tesla but the age of forty buttons is going away. (Seriously, count how many buttons are in your car - then try to remember how often you use them)
