'Black box' in car leads to charges in fatal crash
: "Though not as sophisticated as airplane black boxes, car boxes can record speed, whether brakes were applied and whether seat belts were fastened. Some automakers install them at their factories, but there are questions about whether the boxes violate a driver's privacy and how the information can be used.
Indiana State Police Cpl. Chad Woody said the boxes help their investigations, but not all law enforcement agencies can use the information."
