Ever been biking through a green light, seen a car helmed by a distracted driver starting a right turn into your lane, and gotten that sinking feeling that they just don't see you? Or maybe you were behind the wheel and suddenly noticed a biker just off your side view mirror who seemed to appear out of nowhere. Those blind spots can be killers—literally. Nearly 5,000 pedestrians and cyclists were killed in 2010 by collisions with vehicles.
