Steam on your car dashboard

Following up my post on car driving gamification, I'm going to push it a little further.
Using data from GPS, the car will be able to rate our driving style:
did we drove on that uphill curvy road optimally?
By uploading driving data, it will be possible to compare them with other drivers that drove the same road and crown a real "king of the hill".

Are we going to see Steam on our infotainment systems?

Will we get Steam achievements while driving?
