This is incredibly impossible of a situation to have such an occurence.
Racing CANNOT occur on an oval in the rain. The stresses on the tyres is too great, the speeds and margin for error is too disproportional to be possible.
If there were to be rain at Kyoto Oval on the day of the Kyoto 500, there would be a red flag, the race would be stopped, the cars would be covered, and once the rain stopped, I would call jet blowers onto track to use the heat and air generated by the jet aircraft engines in the blower unit to accelerate drying of the track. For a track the size of Kyoto, it would probably take about 3 hours to dry the track after it gets "lost" (too wet to keep dry with cars running under caution)
So, the only way there would be a rooster tail coming off is if there were to be a sudden massive downpour before we could get the cars back to pits to park them, which has happened, but not too many times before.
But good work, nonetheless. :-)
