We need it. We are in drought.
I did ride to work on a bicycle. Most of the trip it merely sprinkled. About Roseville it began to rain harder and when I came across a bus shelter I used it to get out the poncho and then rode the rest of the way that way. I could have used an overhang on a couple of buildings, but waited the less than a mile to use the free shelter without annoying people in a building to keep from getting wet.
Rain slows you down. So timing was slower, but not painfully so. Since it was darkish, I ran the hub generator light. That too slows me down a little. Ride in was one hour and 10 minutes. Cool beans as far as I'm concerned. Ride overall was 2:25, but the wind was worse on the way home although I sufferecd through no actual rain, just ridiculous levels of humidity.
I saw two very miserable cyclist in the hard rain going the opposite way. I was passed climbing a steep but short hill. He was on a light weight and non-fendered bicycle. No racks either. No lights. And I think he was a little younger. So I've got all kinds of excuses to be dropped in the dust. He also had no rain gear, but it was long before it began to rain hard.
I like riding in the rain. It's hard to get out and do it, but it is fun once you get out there. Its cool and quiet. No where near as awful as most think it must be. Besides it makes you feel like SuperMan. Yay me!
