Known route - driving your car in mental auto-pilot?

Mandy Marder, a doctoral student at university hospital in Essen has done an interesting study, looking at the activity of the brain at different driving situations. It seems that if you are driving a well know route you are less alert than when you drive an unknown route (see press release, we have yet to find the appropriate reference). This is an interesting finding that may help to inform some of our work on automotive user interfaces. Together with trends that move more responsibility from the driver to assitive functions this nay be an indication that driving could be a valid domain for serious games.
