A witness inside your new vehicle?
But various consumer groups, including the Electronic Frontier Foundation, which advocates for individual privacy rights in the digital world, have their doubts. Right now, the information recorded by the black boxes is very limited. Though they continuously gather information, they also continuously erase it. If a crash occurs or an air bag deploys, the boxes retain only the data from a few seconds before to a few seconds after. 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 cell phone 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 percent reliable at this point.
