I watched them previously but its hard for me to look at them again. Especially the last one.

Everything seems to go wrong so fast on the videos. All is fine and then, in an instant, not fine at all. More power to you racers out there, but I'm sure I don't have the stomach for it. You can be a great cyclist, totally on top of your game, then someone else's error can take you out. I'm not criticizing it for those of you who love it, just can't imagine putting the fate of my personal safety in someone else's hands to that extent. Of course there is risk with all types of cycling, we all take on some degree of risk with every ride. I'm sure its a jungle out there, on the Taiwanese MUPs, too.
