The touch controls on steering wheel I have not much issue, working pretty well, other than it looks nasty when dirty and a lil worried that the glossy surfaces will look really ugly once all scratched up. But if you think about it, if you have matte buttons, you know like your laptop keyboard, they will get shiny overtime because of friction with your finger, the surface is already shiny, so actually it might age better 😁
The infotainment sliders, I have avoided those because touching them again makes them look greasy and nasty. But I had developed this habit of never using them. To change volume, I use the steering wheel controls. To change climate, a quick tap of the climate/heated seats icon (bottom left corner of infotainment screen), then I have everything I need for climate controls. Further hidden by it being not backlit during the evening, I don't even remember the sliders exist!
Now the two-switches windows control are absolutely insane, I still stumble trying to open the rear windows, but its not a deal breaker for me.
