I mean, we have known about this for decades now..... At least I remember studying wound patterns for different types of MVA involving pedestrians like 20 years ago in school.
Which was actually one of my main concerns with the cyber truck. Back when more cars had metal bumpers, there used to be a common injury where the bumper would just carve your calves right off your leg. With the cybertruck being a giant stainless steel wedge....... I wouldn't want to be hit by one.
