But with new advances, the boxes might retain data for longer stretches of time. They might also include new information, such as the car's location or cellphone calls that were made using the car's equipment and how long they lasted. Another problem is that black box data are not considered 100% reliable at this point.

To start, the buyers of new cars should be informed, clearly and verbally, that the boxes exist and what they record. Right now that information is tucked away in the owner's manual, which isn't exactly bestselling reading material.
