The real purpose of HDC ( adapted to BMW's from Range Rover , when they were owned by BMW ) is to provide a controlled descent of an snow, ice, mud covered road.
When activated you take your feet off the gas and brake, and the car determines the safe speed considering the steepness and surface conditions. The vehicle controls the throttle and brake, you just steer. It's a little freaky 1st time you use it!
Btw- you can press the gas to speed up, but braking deactivates it....... At least on my RR
