Also, a black box only stores information for 20 seconds around the crash. Manufacturers may also have up to 30 additional data points if they want, excluding, they say, GPS location, video and audio. The information includes vehicle speed, throttle position, airbag deployment times, whether the brakes were applied, if seatbelts were worn, engine speed, steering angles and more.
