I am married with a daughter and consider myself to be car-light. I commute to work and run errands by bicycle when possible. The wife has no interest in being car-free, but lately I've been thinking about and trying to sell her on the idea of getting rid of the car and having a sub-50cc motor scooter for the times when we really need to get somewhere farther away or at a fast pace (emergencies, etc.). There are fairly new (model year 2007) used sub-50cc scooters selling here right now for slightly more than $1000, and they get > 1000 MPG, so that seems to be much smarter than owning a car anyway.
