You are weird. I am a born-and-raised PNW resident and a very small proportion of the population can tolerate having to wear a rain suit to bike home from work or go to the grocery store for 6-8 months of the year.
Do the napkin math on how many of the residents (don't forget children and old people) in your neighborhood bike year round vs. the number who use a car daily. Being on a bike seeing the few other people who bike in the rain is a form of availability bias.
Putting on a pair of snow pants over my jeans and a waterproof shell over my jacket takes... 1 minute? and protects me from basically all our weather.
