This unique device was first unveiled at the KES electronics show in Korea and it is slowly making it rounds around the web impressing and confusing. For me, it does a little bit of both. The RoadBox has a very weak VGA quality camera, and some very non-weak acceleration and speed monitors that can "sense" when an accident is about to happen and begin recording video.
Here is the confusing part—it can only record front accidents, but if it mounts on the windshield there is a very good chance it would go flying upon impact because of that little property known as inertia. Oh well, maybe one out of a hundred accidents the RoadBox could place the blame on another person and not your overly aggressive driving.
