Mercedes Benz have invented a warning system called attention assist to give you a nudge to keep you awake when your making them long journeys in the night on the motorway.

The Attention Assist Program will be able to recognise tiredness related changes in the driver’s personal driving style to warn them to take a break. The device is in its final stages and will hopefully go into production in 2009.
