Though this has been discussed many times, I must say the trend of using touchscreens to replace dials and buttons on cars is extremely worrying. It’s entirely an aesthetic and cost saving decision at the expense of safety and UX.
Most are going back on that. It is just that what is currently being sold was developped years ago.
I use the physical controls, especially when driving. But my navigatrix prefers the screen, primarily because she likes the visual feedback. (Not enough of the physical controls in my car have things that light up to let you know something's happened.)
All I care about is cost, space, reliability, road noise, and range. And physical buttons.
The only reason I absolutely need a screen in a car is for visibility. Pretty much all the risk in parking/reversing is removed when your car has external cameras. The other functions don't make much sense to me. If you wanna play video games and watch movies while you're driving, it better be a smart car.
