That's where I'm at now. Two questions: looking at it subjectively, are you more reluctant to drive to work than to drive somewhere else? Did you go through a period where you would bike in except when it was really nasty out?

So far, nobody else posting has really backed up my theory of accidental psychological conditioning except possibly yourself and plodderslusk. For it to be "aversion therapy" I think it would have to be consistently always unpleasant when we did drive, and feel a greater reluctance to commute by car than to drive somewhere else.
