I'll join in with my own caveats. I want to use this to remind me to not drive the car as much as possible. Caveats:
1. I will ride my motorcycle to commute regularly, probably 4 days a week.
2. Some purchases will require a car, but I will avoid using it for "shopping", walking to the shops whenever possible.
3. We are planning on becomming a one car family next month.
Here goes.
