Different strokes for different folks. IMO, the S2k is geared completely for the driver. Hence, the HVAC/radio controls are at arms reach. Hell, there's even a door to cover the HU. Nothing to distract him/her from the pure joy of driving a car.
I've had this discussion before, but let me summarize:
1) If you are on a track, you won't be fiddling with the HVAC or the audio controls.
2) If you want to easily change the radio station or volume, why not place the controls on the wheel within THUMBS length?
3) If you were to take the S2000 and turned it into a track car, you are most likely taking out the media unit and replacing the wheel, yes? Guess what's still left? All of those useless buttons that aren't connected to anything!
I understand the INTENTION of the placement of the buttons, but from a UX perspective they are completely useless being in that area and just distract the eye from what's important: the dash. If you are going around a corner, you won't be thinking about taking your hand off the wheel to fiddle with the volume control.
Keep that shit in the center media console where you will only think about fiddling with it when stopped/safe cruising speed. If you want to easily change the volume on your radio, place the buttons within THUMBS length on the wheel.
