Yeah, that's better, but of course it means that you either can use that button on the steering wheel for AC, or you can use it for something else. And I am not sure if having reprogrammable buttons in a vehicle is a good idea. If I am recalling it correctly, ergonomics started as something to pay attention to when airplanes suddenly started crashing -- apparently a shape of some control has been changed, and pilots, using muscle memory, would do a wrong thing. Putting more reprogrammable buttons is better than nothing, I guess, but in the end it is trying to fix, with more technology, self-inflicted problems caused by using more advanced technology than was warranted in the first place. And judging from the number of comments I see on HN about Teslas lacking physical volume control, discoverability of the interface leaves much to be desired.
