The notoriously vague EEG patterns are being used in an experiment to control a robot’s movement, promising wheelchair driving in the future.
This can of course be extrapolated and you can imagine easily other vehicles (cars) being controlled by this. Then you can also easily create a system that notices if people are drowsy or sleeping and give a waring signal.
How about controlling your 1200′s??? 
Anyway, until now it is all very limited, see the New Scientist article about it.
