We are currently in the Netherlands. Before that we lived in the Phoenix area. The two of us went from three vehicles including a very large SUV (guzzled gas, but was also fully loaded up fairly often, e.g. used to transport rowing shells, parts and rowers to regattas), a small pickup (used to clear brush, not much otherwise) and a tiny car (my commute vehicle), to one small car. Except for weekend trips to other cities, we drive to work and back and that's it; we walk or bike for everything else. Now that the weather's getting better, we'll probably bike to work some days. Even some of our weekend trips are via train rather than car, and even when we do go out of town we end up fueling up about once every 2-3 weeks.

In other words, you're right :-)
