he didn't go in too hot at all... it was just a kink, not a corner. There are guys standing in the middle of the track up the alternative road (that looks like a corner) so I doubt that section was open. He simply was acuaplaning and tryed to turn, found there was no grip on the front, tryed to turn more, suddenly the tyres grip a little and around you go. It's all too common. Add to that a little lift off oversteer too. He was just damn unlucky with the position of the barrier. But more lucky that he just glanced it and bounced off then hit it direct.
