I'm not taking sides, because I don't know either party, but for that much smoke to come out the back of a car and it to spin out on it's own oil/coolant - it's very unlikely for it all to disappear by the time the Peugeot comes round. Why didn't anyone else spin out (apart from the tankslapper guy at 25s)? They were probably taking better lines through the corner away from the kerb - I wouldn't want to be hitting that kerb at three figure speeds, I know that for sure. Racing incident - combination of fluids on circuit and poor observation of yellow flags. The flag posts are so far away from the circuit at Donington, so it's very difficult to display an "oil flag" - you'd typically wait for someone to spin out in an unlikely place, or find a gap to get onto the track for a brief inspection, you can't just hang one out because there might be oil down, there might not be and you quickly devalue the flag.
