What caused this spinout? (VID)

i think i'd be changing my underwear if i saw a wall comin' up. i think i almost did watching the vid as he came across the grass and what looked like a wall he was heading towards

I know of a couple people that have hit that wall on that course and the wall always wins.
this is easy you guys are making it into a mystery
it was obviously the hard fast high rpm shift while in a turn
caused his rear wheels to spin and started facing wrong direction, he over corrected to fix it, got traction facing wrong way and at that point it was out of control and ended up off track...anyone that drives their car has experienced this and knows never to do a hard high rpm shift while the front wheels are turned whatsoever, its not okay on a high hp rwd car especially at high speeds
Perfect explanation
