Tonight in CTRA Single Seater 1, I slid coming out of the corkscrew, and into...well, through the armco on the right side of track, and then proceeded to fall of the Face of the Earth.

Occurs at approximately 4m30s into the attached replay.

Hmm, I tried sliding into the same wall and went through. I was in SPR so there was no lag.
I did it once but I guess you have to hit it just right.
