Just another suggestion (Ramsey, perhaps you can calrify), but R-Factor race simulator has a kart module if I remember correctly. Perhaps we could record some footage from that for the video… we could simulate line cutting, late braking overruns, fair and unfair blockages etc etc
At least using the simulator, we can try try and try again without time or weather limitations.
Once completed, why not market / licence the safety briefing DVD to CK, Elite, Sepang and any other clubs or organisations such as the new one in Singapore…
