Following up on feedback for the user, for automobiles designers should opt to communicate feedback in non-visual ways. You know which gear your car is by the position of the shift lever. You know when to shift up/down by the sound of an engine. You know what speed the AC fan is at by the direction of the dial and can crank it up and down accordingly. On an older car, a driver can be blindfolded and operate many of the accessory functions without trouble. On a newer car, I wager it's much difficult, especially those with touchscreen interfaces. Yes, there are more functions now, but should they be added at the expense of our safety? I want to be able to switch on the defogger by a simple button, not by diving into a menu.
