Forgot to say in my previous post above, this can be disabled which I did in my Clubsport after the brakes slammed on and seatbelts tensioned as I was reversing very gingerly into a supermarket parking bay causing back and neck pain. The trigger for this was a couple of people wandering between parked cars a significant distance away in another row of cars and the row I was parking in was almost empty of cars (and pedestrians).
I can’t remember the exact settings on the mk8 but I was just reminded of it reversing my car into the garage amongst all the junk with parking sensors screaming away!
Anyway, it’s labelled as Manoeuvre Braking:

that's nice to hear, i remember playing with this in my mk7, but i don't think i have changed the setting in my current car. I'll give it a go, i assume disabling this means i could just exit my driveway and even if i direct my car towards my wall intentionally just for the fun of it, it won't slam the brakes, that right?
