As an SF cyclist, that's not entirely true. Most commutes in the city end up in SOMA, the Financial District, or the Mission, and require little if any climbing. On the way home, even going to areas like the Haight have paths such as the Wiggle that aren't particularly steep and can be done sweat-free.
Obviously some people live and work in areas where a sweaty climb is unavoidable, but far fewer than you seem to imply. And it helps a lot that it's virtually never hot here.
Having moved from Georgia, it doesn't matter if the route is flat when it's 95 and nearly 100% humidity. That's way more relevant to sweat than the SF hills are.
