Has anybody else here taken this course? I became acquainted with this course through my employer. It was an actual, hands-on, over-the-road class offered as "advanced" driver training for fleet management. If one accepts the training (some don't and just will not correct their bad driving habits), it will help to maximize gas mileage from ANY vehicle you drive. Unfortunately, the "live" classes are limited to commercial fleets only. The reason that I bring this up is that many habits learned from the Smith System are the same ones that maximize gas mileage attained from hybrids. In checking for the web site address, I see that they now offer web-based training. Maybe someone here might be interested. They have one course devoted solely to fuel economy. Find it, along with a preview, here.
