I my mind, the main issue was his impact - into a metal pole/support - and why that was there. This is the missed opportunity - an investigation into what other options were and their safety record. My dad mentioned that in his wild youth when he did the bobsleigh, they used a combination of drift snow, pine branches and man made barriers (all softer than a metal beam).
This graphic has focussed on the What rather than the Why or How, so is just showing, rather than explaining. The thing is that showing this is not really very necessary or nice.
Issues within (and pictures) explored in this excellent post too.
