It’s not enough to keep your eyes on the road and your hands on the wheel — you’ve got to stay awake and alert when driving. According to the National Highway Traffic Safety Administration, drowsy driving accounts for more than 100,000 crashes and 1,550 fatalities each year.
Manufacturer-installed anti-driver-fatigue systems have been around a while: In 2007, Volvo introduced a forward-facing camera that gauged steering accuracy, and Mercedes-Benz began offering Attention Assist in 2009. But now, a trio of aftermarket products makes staying awake — and alive — even easier.
