Short of a simple rear-end collision, liability in car accidents can be difficult to prove. However, a new breed of products eliminates some of the confusion by recording video and GPS data to show what actually happened.
The X-Driven DRS-1100 Drive Recorder is such a product. It constantly records driving data, but only saves a file when triggered by a specific event, either a significant shock or the user pressing the emergency button on the unit. By default, the saved file includes 10 seconds of video and GPS data before the event, and another 10 seconds after it. However, it will increase the recording time if the car is moving at high speeds.
