As we move into the 22nd Century, society has been reaping the benefits of transportation systems which now appear to be sustainable. It was not always the case. It was at the start of the 21st Century that decades of bemoaning the state of affairs and talk of making transportation sustainable began to be replaced by initiatives which made possible that which was widely held to be both desirable and impossible. This paper examines the path that our predecessors took in order to achieve this, as well as those which, in their wisdom, they chose not to follow. The reader is transported back to the past to the year 2003. In this time frame we examine the issue of sustainability in terms of: the planning processes used at the time, and their shortcomings; the understanding of time as it existed and the new understanding developed; the process of intellectual re-tooling undertaken in the early parts of the 21st Century to overcome the shortcomings of existing mental models, tools and techniques.
