I can tell you a story: I can trace my interest in hypermiling & ecomodding back to a presentation about "economy driving" I gave to a class of fellow students.

It was when I was training to become a driving instructor, and all the other students were trainees, so they might have been more interested in the subject than the average high school student (considering economy driving was on the curriculum of what we taught).

Fun fun.
