I have to say I'm impressed. He gently and cleanly got off his bike safely. There should be a school course called how to exit your bike at high speeds. Of course, there's only one lesson and then you go home with your bike on a flatbed.
Many years back, I was impressed by another crash by Iannone. I watched it in slow motion about 30 times - the lesson is this: give yourself a low side while your bike takes the high side.
There is definite skill to crashing.
