Drive on the Left
Yes, St. John is a U.S. Virgin Island, however, they drive on the left, so be careful when renting a car. The gorgeous scenery can be distracting, and the roads are narrow and windy. That being said, it is very convenient to have a car on the island for a few days to explore the far reaches of the eastern (dry) side. Taxis are plentiful and hitchhiking is common.
