2011’s Best Gadgets: Driving

Any driver who has ever nodded off during a long trip or drowsily veered into another lane knows how scary those situations can be. Developed in Denmark, the Anti Sleep Pilot ($200; antisleeppilot.com) is a dashboard-mounted device that monitors fatigue, relying mainly on periodic alertness responses that require the driver to touch the device, and also tracking personal data, driving conditions and car speed (thanks to a built-in accelerometer). When fatigue sets in, the Anti Sleep Pilot issues both visual and audible alerts that signal it’s time for a break. An app, for use on a dashboard-mounted iPhone, is also available for $20.
