That isn't rain that is a heavy, continuous mist...
I had that argument with a certain engineer that designed a roof drainage system. He was from Seattle and of course someone from Seattle knows all about rain.
Problem is Seattle only gets about 36" spread out over the course of a year. I was working in Mobile, AL were the average rainfall is 68" and you usually get a lot of it at a single time. I won the argument.
As far as riding in the rain, I use a bike with roller brakes, run my lights, slow down, avoid certain routes and wear bright colored rain gear, typically a rain cape.
