7. Don't speed- it's NOT like the california, new york, chicago freeways, where people speed by the masses and the cops ignore it- the Hawaiian cops drive regular cars and have a single cup size blue light on their roof (they are commissioned to use their own cars- vans, trucks, nissans, mustangs, you name it) so it's hard to spot them- the locals drive under the limit for good reason, not to mention the wild pigs, donkeys, goats, ne ne (hawaiian goose), slippery winding roads you have to mind.
