Maybe it is Time for a New Helmet

I saw this helmet with an odd-looking liner in a bike shop a couple of weeks ago, and snap-judged it as yet another marketing driven design change.  After seeing this though, it seems that there is a lot more to this helmet design than that.  Anyway, here's the very short video and here's the associated journal paper presenting the head impact simulation data.  The small image you see here is a key figure from that paper; click to embiggen.  It's pretty convincing.
