If you were at 0 degrees 0 degrees longitude would you be riding a car or a boat or ship?

At 0 degrees latitude and 0 degrees longitude, you would be located in the Gulf of Guinea, off the coast of West Africa. This area is predominantly water, so you would be on a boat or ship, rather than in a car. Cars require roads, which are not available in the ocean. Thus, navigating this location would necessitate a watercraft.
