> It's doable, but it's also the most time consuming and impractical way of transportation, compared to the other options, so therefor it's bad.
My connection to the center of Stockholm takes 45-60 minutes counting the time to-from stations, I bike the same distance in about 40-45 minutes. I get some exercise, I get to bike to any street I want to in more-or-less the same amount of time. It's bad for you, so just swallow that as a personal opinion but don't come with sweeping statements that "it's therefore bad", this is totally subjective to one's level of discomfort and/or laziness.
I prefer the bike than the great public transportation here for any trip where I won't be carrying more than what my cargo backpack can carry.
I don't agree with the logic of your statement ("it's not perfect for me so therefore bad"), also coming after biking infrastructure is a very weird hill to die on...
