Nice one. That is a good idea.
My navigator and I always record what we believe is the funniest moment or saying during a rally.
Thirty minutes before this pic was taken we have just completed a very fast special test, now the Alpine has a habit when going fast of creating a gap between the hood and the frame which exposes the weather. After the test we were queueing up in a line to start the next regularity when the blizzard started and the wind changed direction. My navigator had been looking down at the maps plotting the next section and trying to keep warm; he suddenly looked up and said "Bl**dy hell, it is snowing INSIDE this car".
It just caught the mood of the moment.
