How do I feel about EVERYTHING moving to a large LCD panel that could play Netflix if I really wanted? I think as long as manufacturers guarantee the interface won't change in very substantial ways since the purchase of the car, I would be OK with it. I would imagine that if the speed limit and engine temperature sudden swapped position, people would get into deadly car accidents very quickly. I know it's not that simple, but you have to realize we're talking about not just you, but 5-7 billion people that may have digital displays to worry about when they are driving. When you scale those UX mistakes, people will die.
So if updates and digital screens are on the way for all cars, I would recommend some basic rules for manufacturers to follow. (Of which I don't know what would be good but it should exist)
