I voted within biking distance, though I don't like to arrive to work all sweaty, and bikes don't go very well in the snow, so I drive.
2.2km, the longest part is actually the last small stretch because of the red light when crossing the highway. Usually have to wait about 2-3 minutes depending on if it turns red as I get there or if it was already red. The green is like maybe 10 seconds.
I'm not sure how people put up with the super long hour+ commutes or the complicated ones where you have to get on several buses etc. That would drive me completely insane. It's time wasted that you don't get paid for.
