I mean they literally were talking about multiple ways. Someone could hit a stereo control and spike volume while turning the wheel which causes a huge break in concentration leading to an accident. That is absolutely possible and could be extremely dangerous in the right situation.
Not really at all. I believe your view is wrong. Just because you believe your high level of intellect makes it impossible for you, you may be forgetting the legion of morons and old people out there driving. Is 100% entirely possible someone could be turning a corner and accidentally does something to cause a distraction and run someone over because they instantly look down away from the road.
Regardless of the persons intelligence, it absolutely can and almost guaranteed has happened numerous times over humans driving careers. The button style just makes these situations easier to take place.
Edit - this isn’t a hit piece on EVs, touch capacitive controls suck in general in cars. Physical buttons are always better, easier to press and locate, and do what you need without drawing your attention from driving.
