All the problems you’ve described are infrastructure abd policy problems We can build climate controlled mass transit stations. We can maintain separated and safe bicycle networks in the winter. We can clear pedestrian pathways of snow instead of plowing the car lane snow onto them. Its all policy and infrastructure. If you make transit the fastest while being convenient and clean, people will use it over cars because it takes less time, not everyone, but certainly enough to make it worth it.

We can’t fairly use the there are no cyclists now argument because we haven’t given them any real options. We need to provide safe and effecient cycling infrastructure to truly see how many people would prefer to bike. If a city had no roads you could make the argument not to build any roads because nobody drives anyway.
