Some of us commute only occasionally, some of us commute enough to drop to N-1 cars, but my solution has been to park "my" car at work indefinitely.

It prevents me from wussing out and driving on those days where I feel lazy, or don't want to get wet (not often in San Diego), and I can still pop out for mid-day errands, or pick up the kids after school if something comes up with the wife (I joke that I would use the bike, but I can't get more than two of them on there with me). Very occasionally, the wife & I need to be in very different places at the same time, in which case I drive "my" car home and leave the bike at work overnight, and we've got two cars to get things done. But otherwise, it lives in the parking deck for months at a time, and the family gets by with the minivan.

Today a friend of mine that often bikes to work told me he liked the idea and started keeping his car at work, so that makes the second person I've ever heard of doing this.

Anybody else keep a car at work instead of keeping it at home?
