Though I'm not certain that is what was meant!
Then again, you can actually ride yourself into a shower if you ride faster. In 2016, while touring in Montana, I could see a band of showers preparing to move across the road ahead of me. I slowed and eventually stopped to let them pass. Up ahead there was a guy on a tractor in a field. He backed up so he would not get rained on.
The very next day I was climbing in the Pioneer Mountains. Had I been a couple of miles/hour slower I would not have gotten caught in the brunt of the snow/sleet/rain event that popped up at the start of the descent from nearly 8,000'.
