I am shocked
Of course, he just made his quota

70 in a 45 with expected rain....
I used to do a lot of long distance touring, and out running rain was obviously dangerous.
Too often I'd ride into a wet stretch of the road but the rain had stopped. And if it hadn't rained in a while, it brought the accumulated road oil up to the surface making it darn slick.
IMO, better to tough it out at a reduced speed than chance a slick road.
But that's something usually learned by experience.
Fortunately, I learned it with out consequences.
On a return trip out west, I was approaching Kansas City that was experiencing a major storm. Extreme downpour so thick it was like approaching a black curtain.
Speeds on the Interstate slowed down to ~20mph as I entered that blackness.
The accumulated water was deep on the Interstate. Probably on the order of 4" or so. No control issues, but my front wheel threw such a strong wake when I ran into that 'black curtain' that it momentarily lifted my feet off the pegs a couple inches.
I followed the car in front of me, off at the next exit where the driver ran into the gas stop and made a telephone call.
He eventually walked over to me and asked if I saw the crash.
In front of him, a car lost control, swerved to the median and rolled.
He was calling the police and requesting an ambulance.
I saw nothing of that accident, the rain was so heavy.
