Hearing your stories is really inspiring indeed !
I've been car-light for two months now.

I did have to drive to work for about three weeks because I had a viral cold/bronchitis, but now I'm commuting to work (28km round trip) 5 days a week, and actually hate driving now because it makes me aggressive and unhappy. I need my daily ride !
Funny, but as a former car enthusiast, I now feel that carrying my body around in a car wastes way too much energy for what it actually accomplishes. And this realization makes me feel great.
I've been car-light before... mostly prior to 2004, when I barely started my car and rode even when it got down to -45C (-49F). But now I'm back at it ! I love the LCF forum by the way, I noticed a lot of great people hanging out in here, making for interesting discussions.
