BMW Speed Limit Display
Combining images of signs taken by a camera on the rearview mirror with navigation-system data about your route, the latest European BMW 7 Series figures out your current speed limit and displays it on the instrument cluster and projects it on the windshield. The technology, developed with Siemens VDO, could arrive in the U.S. in the next year or two. bmw.com

Mercedes-Benz can also determine the speed limit where you happen to be driving, in some models, at least. I don't believe they display it anywhere, but I do know the sat-nav will call the police if you're exceeding it. Methinks BMW may soon follow suit. I hate the NannyState.
What happen's when you go over the speed limit.Does the car stop atuomatically or alert's the police?
It's cool technology, but if they are so concerned about speed limits then why so much horse power in those machines? They need a device for all of the drivers that constantly read and send text messages. Keep their eyes on the road. :-)
