Thanks everyone
Yes, it was indeed quite an experience, and accurately described as a once in a lifetime event.
Whilst Day 2 was tough, it was a great feeling afterwards having done it. And the event was fantastic overall.
Skinrock, yes indeed, it was great trying the two drifting techniques in the i8. What an amazingly versatile car, and so much more controllable and with a "hands-on in-control" feel than I ever imagined, given the computer shenanigans going on with its drivetrain. I love it
