Nissan's camera-equipped rearview mirror provides a clear view in low light

Rearview mirrors aren't always as useful as you might like -- bright headlights, weather or a basketball team in the back seats can make it tough to see what's behind you. None of those should be a problem once Nissan's new Smart rearview mirror reaches cars, though. The peripheral blends a traditional mirror with both an LCD and a rear camera that compensates for bad lighting. Flick a switch and the camera system takes over, giving you a clear view of traffic no matter the road conditions.

What an awesome idea.
