From Engadget Is the VW Space Up! interface developed by Apple?. While houses have been getting larger, the future seems to be in smaller vehicles.
For years now computers have becoming more integrated with the car. At the extreme we won't actually need to do any driving, and can let the car do that while we do something more entertaining or productive. The Space Up! concept, incorporating Apple's Cover Flow is one more look at the car of the future. The interface, hopefully with a lot of options disabled while driving, seems to be another attempt at integration.
