Don’t Honk Your Horn
If you decide to rent a car in Hawaii, which is something that is highly recommended to get the best out of your stay, do not honk at anyone. Most locals are known to be ‘friendly drivers’ for reasons that they embody that ‘aloha spirit.’ So if you happen to be driving and need to overtake someone or get their attention, wave at them instead. You’ll be surprised at how many locals actually do this on a regular basis.
