There are plenty of rural areas, particular in the mountains and the east coast. The road system is good. One can drive around the island in about 15 hours, I would guess. A train circuit can also be done and much more cheaply. The national bus system is as good as any I've seen and the bus is the main mode of intercity transport.
Local transport is mainly by motor scooter and cycles, which there are too many to count.
The parking laws relating to cycles are not ordinarily enforced. There's not much respect here for formal law of any kind. But legislators and the police do not ordinarily expect or demand respect, except in emergencies. Yet there is a Hayekian order of the first rank. The prevailing norm appears to be that everyone can push a bit but not too much.
