This camera automatically "senses" accidents and records the details in the 12 seconds leading up to it and the 6 immediately following it. Of course, if you have the presence of mind while your locked in the grip of terror you can hit the record button yourself to document your brush with death. The one caveat is the camera only records what happens in front of you, so if your get rear ended or T-boned, you're out of luck.
