why scary? Any more elaborate accident is investigated by cops and a lot of data is estimated from eyewitness accounts or skidmarks etc. Now there is a recorder and that should give more accurate data to improve highway safety. Also it would be easier to put blame where it belongs, so no more "it's not my fault, it's the car" excuses, when somebody plows into sidewalk or causes other major accident. Besides, you need to get involved in something major and give technician access to your car to read the data, it's not like the car will report you to authorities anytime you speed.
