Cars used to have modular buttons. It was very common to have a couple of blanks in your infotainment cluster.

My brand-new luxury-brand EV still has blanks. Not all trim levels get the rear fog lights, or a few other things I can't remember. Also, they're used for buttons related to adding the towing package.

Not all markets get all features at top trim levels. A top trim level 5 series in Malaysia is pretty close to the US base model 3 series (plastic trim panels vs wood or textured metal), whereas China sometimes has long wheelbase chassis available, and occasionally you can order power window shades and self closing doors. Even the US doesn't get LWB option here in the states (it's great though, your kid can't kick the back of your seat until they're almost 4)
