I think it's fine for wheel controls to look different though. You're adjusting them when engaged with a task that requires constant concentration, so being able to easily identify the control you want and then use it makes sense.
I'd rather have this than all of them look the same. If you're driving in rain and need to swap to wet tyre mode, but have to spend time figuring out which generic knob does the thing, it's dangerous.
My car has every button and knob share the same design language but all subtly - or not so subtly - different so that the moment a control is touched there is zero ambiguity as to a) how to operate it and b) which one it is.
Appearance also comes into play as one doesn't necessarily have to _look straight at_ something to distinguish which is which or what the position is, merely it being somewhere in peripheral vision may very well give just enough clue so that you don't really have to take your eyes off of the road.
There's a lack of consistency on the wheel controls that make this look more like a UX showcase rather than a usable interface.
Case in point:
- A bunch of rotary knob that perform the same function: to select. But, they all look different and use different ways to represent the selection.
- Some have a lighted indicator, some have a notch, and some are completely ambiguous.
- The 2, 1, *, 0 switch has a hole in it to indicate the currently selected option.
- The plastic surrounding this is is mere millimeters of thickness and I would expect it to break off within a decade.
