Unfortunately the materials really matters with pedestrian motor vehicle accidents. When I first started working in orthopedics and rehabilitation, metal fenders and bumpers were still regularly on the roads and causing very specific injuries.
When a metal bumper hits you, it doesn’t just cause blunt force trauma, it tends to shear muscle away from the bone. There was a specific ankle foot orthosis that was widely produced up until the early 2000s that was meant to replace calf muscles that were scooped off by metal bumpers.
This truck is basically a giant flying wedge of stainless steel, I don’t see any pedestrian walking away from an accident with this monstrosity.
