Ha ha Bullet that is so true, play the game understand the layout then BAM!! The ring as you say does overload you with corners, cars, traction, fear, the barriers. I timed all my laps just so that I had an understanding of my dedication to push a bit harder. My first lap was 12:30s then 11:10 with my best lap 10:20 which I wanted 10:00 so that I could claim to beat a girl in a transit van, but failed.
The Ring is amazing, nothing can prepare you for the sensation. It's like looking at the scariest roller coaster and plucking the balls to get on and enjoy it as well as surviving.
I will have another bash at organising another trip for next year.
