Pay attention drivers - your car is watching you

Research by the Royal Society for the Prevention of Accidents shows that driver fatigue may be a contributory factor in up to 20 percent of road accidents.

This research snapshot reviews the stage reached with driver alertness technologies and what we can expect to see on tomorrow's cars.
