Oh I see, you're talking about the entertainment system of the DX having its controls in the center isle, next to the handbrake.
I was looking at the car system controls below the air vents, hence my wondering what the difference was.
FWIW BMW's idrive and Audi's MMI physical control are in roughly the same spot (idrive's been both below and besides the gear selector, MMI's usually been above or below though both have basically surrounded the stick: https://www.picclickimg.com/00/s/MTE1MFgxNjAw/z/xvEAAOSwll1W...).
And though recent generation MMIs are apparently touchscreen-only, BMW has retained physical controls next to the shifter: https://cdn.bmwblog.com/wp-content/uploads/2017/10/BMW-6-Ser...
