I am a new model S owner for about 2 weeks. I really like the big touch screen when use it for navigation and back camera and settings. But I found sometime I miss the buttons and nobs in my old car. Especially when I driving high speed on highway. when I want to switch audio source, open/close sunroof and adjust A/C, I always need look at the screen and find the place to touch, which feel unsafe. For my old car, I can always touch and feel and don't need look at the them. Even I can customize the buttons on wheel, but it's not enough. Is that just me feeling this way?
