That's a valid point and I wouldn't disagree (though I can't help but think that you're generalising a bit too enthusiastically with your comment about managers). But my post was about the effect of pollution on potential and actual cyclists. I was noting the dilemma of the situation in which potential cyclists are deterred by a problem that greater numbers of cyclists would help to negate. I don't care too much about how many Americans are willing to ride bikes to work since I'm not American. But then, I don't much care about how many Britons do, either. I also don't care very much about congestion; I just cycle through it. Technically, my job could be done from home. But even setting aside the professional advantage of being able to speak spontaneously with colleagues, I personally would not want to work from home. I appreciate the division between my professional and personal lives that is created by the act of travelling to a different location. I also appreciate the social interaction that I enjoy when I'm there. I understand the benefits to the environment that would accrue if internet connections were to replace cars as the means for commuting to work, but personally I'm happier to cycle.
