Yeah I've thought about this in the past in the context of software development "sane defaults"...here in NYC just going about normal daily activities easily results in 3+ miles of walking per day. The "default" lifestyle involves walking to transit, walking to shops etc. Plenty of people use cars, but in very many situations it's more cumbersome than walking/transit. Whenever I visit family in the midwest it can be a bit of a culture shock: by default you might find yourself walking a few hundred feet per day. With garages built into every house, few sidewalks and office parks/shopping centers that are only accessible by car, you have to make an explicit effort to get any exercise.
