I do not favor racing in the rain.
I raced motorcycles for 13 years, I never liked the rain.[make that a big, bold period!]
As I realised that it gave me no pleasure, I began to start a race when it was wet and pull into the pits after a few laps, sometimes even on after the first. Once I started doing that, I found that others had pulled off and were waiting, as I was, for a white flag[last lap] so we could go back out to "finish" the race.
I can't tell you how many championship points this won me during a season but I certainly won more than I lost as so many others dropped[fell] out. I never lost a championship because of it.
Unless you live someplace with radical weather, from what I've seen since participating in snd watching races over the past 42 years,
THERE ISN'T MUCH RACING THAT HAPPENS IN THE RAIN.
Get over it , drive on a dry track, with slicks, it's the way it was meant to be.
All this C#$& about half a track being wet or dry, weather changing during a race, all BS.
