If exposed to weather it is an automatic fail. Sorry, that is just how it works. From any transportation alternative that is no enclosed it always comes down to comfort. One day it is too hot, another too cold, or too wet, and on and on, until the excuse is no longer needed as the alternative mode is parked. So any bicycle or pedestrian friendly environment needs weather protection as part of its design. It does not…
If it's hot I pack my work clothes and change (and shower if needed) at work.
If it's cold I dress warmly. It's amazing how quickly you warm up when pedaling more than a few miles.
If it's raining I wear a rain jacket, and the fenders on my bike keeps water from splashing up on me.
So no, weather is not an automatic fail. It's just a mindset change if you're used to be in the enclosed bubble that car provides.
