> Stretching your arm all the way across the dashboard to fiddle with a vent may not be ideal from a Fitts-ian standpoint, but you can accomplish it without ever taking your eyes off the road. The Tesla’s touch screen, though, makes no-look operation impossible—which raises the stakes for any non-ideal button positioning. Does it actually? It seems to me whether it's a physical button or not, a glance is usually enough to hone in on it. If you're going for completely blind groping for a knob type action I guess I understand, but I don't do that. A fixed button on a fixed screen should be almost as easy to fix in muscle memory as a physical button or switch. Small codicil: I much prefer physical buttons and dislike the tendency for physical interfaces to disappear.
