Halo saves another life.

but you dont need the roll hoop to be high then the front of the halo, the rest of it can be a similiar crash structure exactly for the reason to be ground away and reduce some of the impact and here you exactly see where you need the stronger roll hoop which you can see in this picture perfectly where it lines up with the front of the halo,

so either it broke through the flip at the end of the gravel trap and landing between the fences or something happened with it when they retrieved zhou or the picture is deceiving and the actual height is still enough for clearance of the head. we can only speculate
