I don't have kids, but tentatively expect to in the next 5 or so years. Market resolves n/a if I don't have a child by 2030.

The primary purpose of the ride must be for transportation. Toy cars do not count. A one-off joy-ride just for novelty purposes does not count.

I currently live in SF, but wouldn't be surprised if I move to a suburb later in life. I don't have a car, but my girlfriend does.
