Obviously, I am not the first to wonder what can be done within the framework of the present market-oriented, mobile, time-driven, suburban society to create more livable, socially integrated communities. Indeed, the literature on "sustainable transportation," "smart growth," and "new urbanism" is too vast to summarize here (for examples, see Steg and Gifford 2005; Turton 2006; MIT and CRA 2001; Dearing 2000; Progress 2000; Geller 2003; EPA 2008b; Calthorpe 2002). It appears, however, that most proposals for sustainable transportation enhance walking, bicycling, and other transit modes at the expense of convenient automobile use and single-family suburban living. Realistically speaking, such proposals are thus not likely to lead to large-scale transformations in urban living and driving, although they might be effective and benefi cial when targeted to dense urban centers. Rather than attempting to force people out of their cars or suburban homes, this proposed system expands travel and lifestyle choices at essentially no private cost, but with very substantial social gain.
