How is the “potential for injury” figured?
The forces generated in a collision will tell not only how fast a vehicle or occupant was accelerated, but will also tell which direction. Knowing both of these things will lead to an understanding of what, if anything, they might have hit in the vehicle and how hard they hit it. G-forces can be related to activities of daily living based on studies performed. Crash testing of thousands of vehicles, documented in many technical papers, can be used to compare injury potential.
