If the main goal by aquiring a BMW is the driving per se, then you need only a basic cockpit and simple instrumentation. However a lot of BMW buyers are interested in technology and more or less useful gadgets. Stuff that might be taken for granted in a couple of years - or maybe it will flop instead.
The good thing is that you can make your own choice, hence the large option list. There is no correct answer to how to equip you BMW. Or rather: All answers are correct.
