Just like the infamous "black boxes" (aka- event data recorders) found on airplanes to determine "what went wrong" when an airplanes crashes, cars can be equipped with similiar technology. It also has another perk, it helps Automakers improve their safety equipment.
Now Congress is looking to make these a standard feature of every vehicle sold in the United States of America, GM is all for it. GM also has been putting "black box" technology in vehicles since 1995 to save data during accidents that airbags are deployed. The recorders save the last few seconds of data before a crash from a number of different sensors. GM is not only welcoming this legislation but also think the information should be made available to determine the true cause of accidents.
