So I'm lookin at an 02 WRX wagon, and was lookin at the safety ratings at http://www.motortrend.com/cars/2002/subaru/impreza/wrx_wagon/1727/crash_test_ratings/index.html
Now I understand the star ratings obviously, but the Head Injury Criterion, Chest Deceleration, Femur Load, Pelvis Deceleration, and Thoratic Trauma Index are a different language to me.
So, how do you interpret these numbers? And what is a scale I can go by as to what is a good number, what is a perfect number, what is horrible, etc?
