Automotive Electronics: Death By Wire Or Digital Savior?

 Paul Whytock, Editor-in-Chief

New technologies like lane departure warnings, forward collision warnings, blind-spot detection, and adaptive headlights could prevent or mitigate one out of every three fatal crashes and one out of five crashes that result in injury. Yet electronics also were involved in 47,000 crashes related to driver distraction in 2012. How can we do a better job of staying ahead of this dangerous curve?
