There is a ferry to the island on which you can take your car to the mainland ;)

Nassau, the capital of the Bahamas, is roughly shaped like an American football a bit under 20 miles long and 6 miles wide at the widest.

Not Just Bikes did a video a while back about how car dependant it is. Car dependency is unfortunately often self-reinforcing because car infrastructure is ugly and dangerous for people who aren't in cars, which pushes more people into cars.
