Mercedes-Benz Research and Development is using the Google Glass to create a navigation system that does not require you to look down, nor type in directions more than once if you are moving from walking, to car, back to walking again. On top of this, M-B is also looking into creating an Android-based infotainment system (which i think is the future of infotainment systems.)
Though both these projects are currently in development, I would guess that we can expect them in cars in the near future. It's about time that car companies give up trying to build better computers than Apple, Google, and Microsoft. Just choose Android or Apple and start building on their platforms. it will make everyone's lives a lot easier.
