Its a bit like those people who complain about too many cyclists in summer. They ask where are they during winter months?
Well, they are taking alternative transport because they don't like winter. Almost like asking why people don't put the top down on a convertible when its raining. Actually I should add that to the "pet oeeves" thread.
Anyway, the point is, don't fret about it. Cycle as much or little as you like.
