Also did you know that, if you are on an incline, and you let go of the brake with the car in D or S, the M5 will start to roll backwards, but it will only roll backwards for a few moments before slowing itself down and then it will speed up again and the slow down again, until you press on the gas pedal again to start moving forward. Pretty cool. It's much better than the E60 M5 hill assist function, where in that car, the M5 will let itself just keep building up speed from rolling backwards on an incline.
As long as you have your seatbelt on. No seatbelt = no auto release of handbrake.
