Since their debut 13 years ago, in-car night-vision systems, which identify pedestrians approaching a roadway, have arguably made driving safer. But they come with a pretty big blind spot: animals. Each year, drivers in the U.S. strike about a million deer, causing 27,000 human injuries and $3.5 billion in damage. This fall, Swedish safety-system company Autoliv and Mercedes-Benz will roll out Night View Assist Plus on the 2014 S-Class. The system identifies people but also picks out cows, moose, horses, deer, camels, and even wild boar.
