Picking up my F30 320i this week (or early next week, depending on when the car arrives). My first BMW (and first continental car). So I have been reading the F30 user manual. There is SO much features and functions that I am wondering whether I will use them at all! Can turn off the DSC, got traction control, got auto cruising (which I never use anyway on my current car), and auto cruising also can adjust by speed and distance from the front car, can choose different drive modes, got blind spot warning, swerve out of lane warning etc etc. So confusing!I would like to know from those who drive a BMW, what are the main features/functionalities that you actually use on a regular basis? And what features do you just leave on permanently and not touch at all?Thanks,whw
