Yeah, now that I think about it, the turn signals are (usually) well designed. In some vans/trucks they suck though (you have to twist a knob rather than a down/up motion).

Windows are again usually pretty good. However, in my mini cooper, the window switches are located in the center console, unbelievably bad design in an otherwise pretty well designed car.

I mentioned steering, gas and brakes primarily because they are the same for almost all cars.
