It is somewhat impressive though. Having owned a superbike before, I can see how you can become "desensitized" to that feeling of fear.
It actually is quite a rush!! Adrenalin is really pumping. The bigger the risk, the awesomer the ride! Obviously I've never done this sort of thing.
But there is a point where your knaters outmatch your luck, as there are just too many variables out of ones control, and then you are very dead. It's why I prefer not to commute. I get adventurous, take chances, and I could get killed, as will this oke if he doesn't tone it down.
