Actually, if you look really hard at the end of the crash, something seems to slide underneath his head, unless that's his hand...
The crash was much worse live I think, because you can watch it now and think "well I know he's safe, so...", but it seriously was bad live. The thing that shocked me was that the car flipped over, so that gives an indication of how much force it takes for it to do that flip so quickly, and then travel as fast as it did in to the wall.
On a lighter note, it's a sprained ankle and light concussion, so that's all good. Plus, for the first time in like...ever, F1 has dominated the back pages; hell, Hamilton filled up most of the Sun's front page even.
