None of this is rocket science, it just takes a bit of experience. Half the battle is developing a culture in which cycling is treated as an ordinary mode of transport rather than a sport. In places with a very strong cycling culture like Amsterdam or Copenhagen, you see all sections of society on bicycles - ordinary people in ordinary clothes riding ordinary bicycles at an ordinary pace.
My personal opinion is that the car culture in the United States creates an environment where everyone is enforcing their own arbitrary set of rules on the road, and in most cases, cycling is very much against these rules(regardless of any legal or logical basis).
Reading any comments, as a cyclist, on almost any social media platform regarding cycling becomes disheartening to downright scary. It's as if there's not even a discussion to be had.
any source for this extraordinary claim?

But our summers are certainly hotter than Copenhagen and Amsterdam. I didn't look up Berlin.
If you wear shirts that breathe a bit and use a pannier instead of a messenger bag it's not so bad. I use REI hiking shirts and leave the top two buttons undone to keep the air moving.
Coming home can be a bit worse because it could be >90 degrees but in the cool morning it's fine.
Fortunately we do have showers though. Some of my coworkers have 20+ mile bike rides into work and they really need them. Mine's only 3.5 miles.
