They have one freeway they call expressway. It doesn't even go the entire length of the island. The picture shows exactly how narrow the streets are here. Some streets seem one way, because you can hardly fit two cars down them. But actually I have only seen one or two one way streets. The maps don't have all the roads on it either. I would say that 95% of the roads/streets do not have street signs or names on the street. They give directions like turn next to the McDonalds. It is like once you turn off a main road, you are in a maze of little narrow roads, with houses sitting right on the road. And Dydo machines (vending machine that has water and coffee and juice too) along the side of the streets everywhere. And people literally stop in the road, put their hazard lights on, and get out and get a drink from the machine or run into the store. They pull to the side of the street, but remember the street is so narrow it seems like they are in the middle of the road.
