I know it’s been a while since the original post was made, but the poster hasn’t considered that this isn’t practical everywhere and all the time. For example, a 2 mile bicycle commute in Marquette MI this last winter (2014) would probable have been fatal several times just due to the effects of cold. When the wind chill is -70, if you’re wearing enough to keep you alive, I’d bet you couldn’t ride a bike. Then there’s the impracticality of trying to ride to work with several inches of snow on the road/sidewalk.
It’s a great idea in the places where the weather cooperates and sidewalks exist to ride on (there’s no way I’d ride on some of the roads I’ve driven on to commute), but it puts restrictions on where you live relative to where you work (no 30+ mile commutes by bike), as well as shopping, etc. I’m glad you’re enthusiastic and able to do it, but your post clearly ignores these issues and asks us all to do it as if it were possible; it isn’t and hasn’t been for decades.
