Actually, I think the car industry has this pretty well figured out. The restyling is because (most) people don't want to have the same car as everyone else.

Actually, I think the car industry has this pretty well figured out. The restyling is because (most) people don't want to have the same car as everyone else. Any given model comes in a dozen colors for the same reason, and because there are people who literally won't buy a car unless it comes in their favorite color (and base their decision on almost nothing else). "Auto-everything" is about "don't make me think" design. People just want to point their cars where they are going and be done. They don't want to worry about: did I lock all the doors? Did I dim my high-beams? When should I shift? Will I remember to pump the brakes in a skid?
