Driving safety can be achieved by predicting e.g., about 40,000 per year in the USA alone , but such imminent falling asleep at the wheel. Several methods of statistics underestimate the number because they do not include most crashes due to fatigue or those where early detection have been investigated by continuous monitoring of physiological and behavioral parameters. drowsiness was not apparent, so this kind of risk actually Requirements for noninvasive, unattended, personal adap- involves millions of drivers.
