How About a Vehicle to Help the People Get Around More Quickly?

The story takes place in a world where the people are living in harmony with the rest of the earth. The gods and goddesses decide to reward them by giving them something that will make their lives easier. They suggest an engine power, four wheeled vehicle to help the people get around more quickly - but not before they fasten their seat belts. Or how about a powered flying vehicle so it can soar above the clouds? No, no, no. I'm thinking we give them something more useful, more practical, something like food. What is rice?
