And we can talk about how maybe you should because it's better for you, but this brings up a larger issue: when it comes to how whole populations behave, comfort is a factor that can't be totally ignored. Basically it creates a trade-off. Some percentage of people will decide one way and some the other way. This is going to affect adoption if you try to build a city around this idea. Incidentally, there are also issues in hotter climates. Here in Texas, it hit 100°F (37.7°C) more than 50 days this summer. And it doesn't get cold at night. You can try to avoid the heat by biking to work early, but even at 6:00am, it might still be 80°F (26.6°C) and humid. So you will arrive sweaty, and if you don't do something about that, you will smell bad all day. (The ideal is if your office provides showers.) You're also probably going to end up taking two showers every day since you are sweaty when you get home.
