I didn't vote in the poll because I do own a car but I am interested in the demographics of the ones that are car free.
I agree there should be a choice for "too poor to afford a car" and that there are many who are car free that don't have a computer or take part in bikeforums.net.
I try to do as many errands on the bike as possible, but outside of my commuting, I only do about 1 bike errand a week. I attribute this to having a family. It isn't suprising to me that the large majority of car free people don't have families. Just about every errand I do in my car, I do with a family member, and many of the car trips I make involve a long distance or heavy load that would make it undesirable to do on a bike.
At least I've managed to reduce my driving by 25% due to bike commuting, and I almost never am in a single occupant vehicle.
