Yeah. It's impracticable for many jobs but it would be a shame to reject cycling out of hand because of potential weather issues.

I just wear bike shorts and jersey whatever the weather. I have work pants and shirt that I change into in the restrooms at work. There's no shower. I have wet wipes and a little hand towel.

It's pretty rare that it's raining heavily enough for long enough that I can't get to work between downpours.

By far the most important thing is mud gards on your wheels.

As I said, it's not for everyone but I suspect that it's not actually prohibitive for most people.
