Same here. It's not only BMW, but almost every other brand I had before. It seems it's a common theme done by manufacturers for safety and legal issues. I can't find article about it, but it's done mainly for safety issues. GPS performance boxes 10/20Hz like Vbox or Draggy can measure true speed more precisely.
