CAR ACCIDENT SAFETY:

Most people aren't aware that their cars contain black boxes. Collecting electronic information helps reveal exactly what happened inside a vehicle prior to a crash. -- I have obtained "black box" information in an I-70 trucking accident case. The data helped us determine the speed of the truck, prior to the crash, and whether the driver applied his brake before plowing into my client, who was stopped in an I-70 traffic jam near Montgomery City. This is an interesting story from NPR on the subject.
