Putt-putt--Sustainable vehicles in the world of Ordinary

In Where I'm going--Short term I listed, in no particular order, some of the foundation issues I've been researching for Village of Ordinary. The second of those is a three-parter: How much do the people of Ordinary rely on vehicles, what kind of vehicles do they use, and how do they power them? One thing for sure: any vehicles in the world of Ordinary must be sustainable.

I'd like some help with this one. Please join the discussion. It's a big subject and one I haven't had much time to research. So far we have seen villagers utilize a truck, a small car and an airplane.

Broad-picture questions to answer:

1. What types of vehicles do people in the world of Ordinary employ? (e.g., planes, trains, ships, trucks, cars, motorcycles)
   
2. How are the vehicles fueled?
3. Are all vehicles fueled in the same manner?
4. For what purposes do villagers use vehicles?
5. What other forms of transportation do they use?

Vehicle musts:

1. Sustainable, local fuel sources
2. Non-polluting
3. Long operating life (no more planned obsolescence!)
   
4. Shared
   

What questions/musts am I missing? You are invited and encouraged to share your thoughts.
