I think this phrase (the transportation pyramid) ought to be driven into every schoolchild's skull and tatooed on one of thier hands:

If you can't walk it, bike it.
If you can't bike it, ride (a train/bus to) it
if you can't ride it, drive it
if you can't ride or drive to it, take a boat to it
if you can't float there, fly there.

this one needs a little polishing, but the idea is to enculturate the idea of preferring the lowest energy transport method available to the task. (flying is for those who don't know, the most energy expensive method of transport)

oh, and @tightwad: mas uno por Cuba! (+1 for Cuba) I'm not saying they've got things perfected politically, but they're definately the best example of how to survive peak oil.
