For the X5 it should be standard in my opinion. Great feature and this was one of the first options I included on our new one. I had it on my previous 6er and liked it while driving around in the city although I don't like it when you start playing with the car.

Don't have it on the M6 (not possible) and there certainly is a reason for it but on the X5 ... you need this.
