Couple of years ago, I rented a Model S while I was out in Vegas to see how it's like. I counted 3 taps to get the sunroof open... WHY! Just about every other car out there, you reach up and pull on the switch.
Even after installing Openpilot in my car, I still don't like taking my eyes off the road when I drive. Until cars no longer come with steering wheels, I prefer buttons over a touch screen.
