Last year on the way to SSITS I drove 8 or 9 hours in flooding rains. Even had hail bouncing off of my helmet at one point and it was a brutal day. Most of this was interstate travel with not one instance of hydroplanning. Then on one of the group rides in heavy rain at about 40 mph the rear tire lifted and I missed a guardrail by inches. Two of the 5 of us in the group hydroplaned while the other 3 didn't. We were all riding very carefully and luckily neither of us crashed. I could see no reason why 2 of us in a line had an issue other than the luck of the draw.
After that my belief was that I needed to park and wait out heavy rain and to be extremely cautious of puddles or water running across the road.
