Lifelong car-free homeowner here, (2nd home, this one paid for), with child and spouse who's never had a driver's license. 14 years ago we were 2 liberal arts grads with $50K of debt, and we didn't inherit anything in the interim. We fly maybe once a year, take public transportation about 3 times a year, a carshare car maybe 5, and bike or walk everywhere else. Our home is in a quiet leafy neighborhood laid out in 1910, when bicycles were the fastest thing on the streets (they still are, often). They've torn up the streetcars but the bicycle technology has gotten better and there's this internet thing. We've lived in 7 cities together over the last 20 years without much trouble. We would simply never consider living anyplace designed with automotive transport as a norm in mind, nor take a job we couldn't get to without a car. We're self-employed now so it's even easier; the smugness is just unbearable. Getting out of the trap once you're in it is surely harder. Xtracycles are great for hauling family, groceries, construction supplies etc. It's all been said before. It's more a sociological and psychological challenge than a logistical one.
