That's a popular place for the local motorcyclists and sportscar people to really push the limits of their driving skills. As you can see, many of them push it well beyond what they are capable of. That corner in particular is bad, if all the videos on youtube are any indicaiton. It looks like it goes from on camber to off camber just past the apex, which is a good way to crash if you don't know it's going to do that.
