I don't know about cup holders - but it's been definitely shown, that replacing actual physical knobs and buttons with a touch-screen does hurt safety. The thing with media controls is, that you can use those only when it's safe to do so. You're not gonna change the radio channel or music-playlist while going through a busy intersection. But many of the functions car manufacturers are moving from actual buttons to their touch-screens, aren't that time flexible.
