Bloody hell, that was very hard to watch indeed! If you don't know the road, ride easy until you are familiar with it. That bloke had numerous mistakes to wake him up to the fact he is doing it wrong, but he clearly ignored them. I don't wish accidents upon fellow riders; but sometimes, just sometimes, a low speed tumble into some bushes is what is required to wake some riders up!
That road does look like GREAT fun to ride though.
