I'm sure that would defeat he object.

You apply the handbrake and the car doesn't move. I find it hard to believe that BMW designed a retarded system different from the rest of the Universe  |
You have obviously not lived with BMW cars. This parking brake setup has hardly changed in design since my first E12 528i in 1976. My F11 5-series with its 'electric' parking brake, is the first BMW I've ever used not to have this movement.
In fact it is quite a clever design on how it works as a drum brake, and how it is adjusted, but does need to be kept in good adjustment to keep the 'rock' to a minimum. It isn't a big amount of movement, but is there, has to be due to the way it works. And it increases as the shoes wear, until adjusted again.
