Both of those videos are incredible. I had not seen the first one before, but McLovin's one has made the rounds I think.
EDIT: I hasten to add, and this applies with cars/other vehicles as well as bikes:
It just goes to show you, NEVER give up on driving out of a bad situation. You obviously can't save yourself in all situations (or maybe not in any except a small minority) but always stay committed to the turn, the braking, etc. - whatever the situation calls for. I have definitely had a few times, early on, in the local mountains where I was certain that I was done for, having blown a turn. Every time I have saved it even though I had that sinking "oh sh*t, I'm crashing" panic feeling in my stomach. You have to swallow that feeling, and attempt to relax and focus. It is absolutely critical to believe you can make it through the turn/stop in time/etc.
One time we were riding downhill (mountain bikes) up in Big Bear in the summertime, and it was one of my first times. I was going what turned out to be way, way too fast for this one turn and suddenly I was very rapidly approaching a sheer cliff drop-off. I applied as much brakes as I could, and steered as much as I could, and barely avoided a plunge.
