At the same speeds as the guys that crashed?
Yes and faster, I was outside of Tucson in an out and back ride going up Mt Lemon sky opened up. Been on Mt .Palomar and on Banner Grade in similar conditions, big difference was I didn't need to get a wheel. If you get gapped in a pro race,rain or no rain, get crushed in a cross wind and you lose contact your day is over, maybe your race if you miss the time cut.
Me riding around with friends and giving each other distance and a huge difference.. Designated regrouping points.... In bike racing it's opposite, if someone loses contact with you they don't want to see you again, that the goal. So bike is the same, speeds, conditions are the same, difference is drafting, tailgating in the rain on purpose as a point of survival. Nothing Remco or Roglic can be taken seriously, because both riders are never scared, never go to a race, sun,rain, whatever, they are never thinking that they are getting dropped. Lots of these guys are holding on for dear life.
I have zero idea how a race or the UCI could come up with some safe following distance rules when conditions turn to schit. I know for sure that if I am some water carrying grunt and it's pouring, I am keeping the wheel in front of me and willing to follow a little close to make it, make next selection.
I consider myself a below average bike handler and my main point is equipment has little or nothing to do with these situations, surprised not to hear some tin foil talking about hookless rims before people hit the pavement, people were still midair as disc brakes were the cause!!
