I have committed to only driving when I absolutely have too.
With an ecargo bike and no fear of weather it’s rare to see me on 4 wheels.
Ride your bike as much as you can!
It’s just water.
 The real challenge is finding rain gear that you’re comfortable wearing. After living years in a place with heavy rains and snow, I really like the quality of showers pass gear.
When you’re wearing heavy duty, rain gear, you’re likely to get very warm and possibly very sweaty. I mitigate this by wearing wool for breathability and riding at a slower pace so I don’t overheat.
