- bobthepanda 2y agoOh does it? Where can I read up on that?
- mitthrowaway2 2y agoI don't know of anyone who's written about it, unfortunately; I discovered it in the course of my own analysis of Euro-NCAP standards as part of a work project. The test protocol is here: https://www.euroncap.com/en/for-engineers/protocols/vulnerable-road-user-vru-protection/ https://www.euroncap.com/en/for-engineers/protocols/vulnerab... I used to be very excited about Euro-NCAP but when I actually researched it, I became fairly critical. It only measures AEB, and leg impact and head impact against the car, with very little consideration put into how the general profile of the car affects the collision kinematics. Whether the car pushes pedestrians onto the ground or throws them up in the air, it doesn't matter -- only the initial contact between the car and pedestrian is measured. (And while representing the pedestrian by a disembodied leg and a disembodied head). It's had a good influence in some ways, most importantly by testing head impact at various points on the hood, which has forced automakers to reduce stiffness and add more space for deflection between the hood and the engine block. I think in other ways, it's helped accelerate a trend towards brick-shaped vehicle fronts, because they perform better on the leg impact tests. I personally believe this will result in fewer leg injuries but more deaths.
