Maybe statistically, OK. But if you have a nice commute it may be likely the best part of your day. I have a mostly flat, 40 min bike ride in the woods every day, and it is my "me time" that I cherish and lets me unwind before and after work. Definitely not "lost time".

You have kids don't you? That seems to be a consistent feature of people I meet who espouse the virtues of going to work.
Yes. But my liking of bike commuting is maybe more related to the fact that it is a positive change from using public transportation, where I felt really miserable (had to take two crowded buses with an indeterminate waiting time in-between).
But you are right that having kids changes one's view to work... often, after an intense weekend, I go back to the lab and say "finally! I can relax and get some work done".
If that's the absolute best way you can imagine spending those 40 mins, you don't lose the option to do that.
