I think you're right. I am thinking of old TVs which I remember using a single remote with all functions in it. Moreover, I was responding to the specific argument about 5 vs 50 buttons to do 5 vs 50 things. > You can't have physical buttons for all this stuff. It just doesn't scale. Definitely. Like in the F-15 video, the controls near the elbows were rarely used (essentially "hiding" them out of sight). So may be a good compromise is pick 50 most used features, create buttons for those and then leave the rest of the 150 features in the menu system. I haven't used a modern TV in over 10 years, I hope the remotes still have decent number of buttons. [1] car appears to do everything right. [2] is worse because it feels like what you see is just the tip of the ice-berg. [3] had to be like that because there was nothing more to be done. It didn't need more controls. Unrelated: A turn signal stalk is a brilliantly designed UI control. If famous designers we know - say Jony Ive - and if they don't know what a car is and you ask them to design a dashboard, not in a million chance that they would come up with a dangling stick behind the steering wheel that translates LEFT/RIGHT signal > DOWN/UP stalk movement > ANTI-CLOCKWISE/CLOCKWISE steering movement. It is totally genius and not obvious at all unless you've seen a steering wheel and a turn signal stalk before.
