My takeaway from that article was the same as Dan Lloyd said:
"The only training you get is when it actually happens. Other riders might disagree with me, and I've heard once or twice riders saying that through training they could crash and not hurt themselves, but in my opinion it happens so quickly there's so little time to think about how you roll."
My one crash in a crit years ago was like that. Clipped my front wheel, boom, on the ground. No time to react.
