Road Map Paragraphs: An Outdated Metaphor?

In teaching legal writing, most of us encourage students to write road map paragraphs, that is, a paragraph in the  introduction that informs the reader of the organization of the ensuing discussion--where you are going. This metaphor works for readers who use maps. However, a  few days ago, my 22 year old daughter refused  to take a road map with her on her trip out of state. She told me  that she doesn't really understand how to use maps. For her, GPS is the replacement. For others,  it's Mapquest. Perhaps we  need  an updated  metaphor for  the new generation of students.
