Click this link, forward to 2:00 and at 2:05, click Settings and slow the playback speed to 0.25. Watch closely, 2:09/2:10 and again at 4:00; this crash was one of the most violent involving a side impact I've ever seen and to me, explains why John is still hospitalized and there's been no further updates. They may not know because they're still evaluating what's going on inside John's head from an impact that was likely in excess of 50G. I believe the only reason he's alive is because of safety measures implemented by his own team after the death of John Medlen.
