If you have mutability in a small screen in front of the steering wheel, I would assume you could put NOTHING on that screen. The idea, is that you put what you want - or not.
I think a small display in front of the steering wheel that can be modified to show what the driver wants want be just a great addition. You want the speed up front, you got it, GPS directions, etc. At present, I will likely have a GPS app on my phone mounted in front of me for easy access.
