This makes driving and operating stuff a lot safer than things like the Volvo
I obviously no longer have my Volvo, but you do not need to touch the touchscreen. There were knobs for all temperature things, and all safety things. And the steering wheel controls allow one to do the rest and control the display from there, and there's a heads up display.
I felt that the touchscreen mostly was helpful before driving when setting a route and entering an address and then choosing the pin on the map... and whilst driving I never needed to do that.
I wouldn't mind a touchscreeen that software disabled the touchscreen itself when the car was moving above a certain speed (say 5mph).
I'm really happy that research shows that which we mostly all knew... hardware controls are safest and best for an interface. But I don't think the way forward is to remove them entirely, but instead it's best to control their use.
