I think one worthy goal is, as lph mentioned, not to drive to club rides and such. If you can't cycle to the start of a ride, just cycle locally instead. I gave up club riding partially for that reason -- I don't want to have to drive my car in order to ride. For big events, you could always make an exception b/c the mileage ridden, charitable cause, and special occasion of it could make it worth driving to.

We too are car-lite. We recently moved from the country to town, sold our second vehicle (a big ole Ford truck we were barely using since moving to town), and we take the bus and walk places a lot now. We were riding a lot more, but then it got really cold. I work from home one day a week. My DH walks and takes the bus to his (volunteer) work with Habitat.

So currently the car is used mostly for my commute to work 4 days a week and the (very) occasional errand or party that we can't walk/bike/bus to. And travel. So we're not purists but are driving MUCH less than when we lived in the boonies.
