In fairness, he's never driven to this job - he unexpectedly changed jobs about a month after we flogged the car and the new office is startlingly conveniently located. And he usually walked to the old place, even when we had a car, until he started having the nursery/school run 3 days a week, which was a 3-4 mile round trip at the beginning and the end of each day.
I'm just somewhat tickled that he's only just discovered quite how liberating it can be to own a bike now, when he's in his mid 30s!
