no shade but when he said honolulu i assumed he meant the entire island out of ignorance. Most people who have never been or lived there refer to the island as "honolulu" or "waikiki". That area is newer construction but not like brand new. I lived in both cities back 2012 ish. It was newish for hawaii. The whole island unless things have changed is pretty much older construction but makes sense since they dont get anything but summertime weather lol.
That's definitely true about people getting the whole island and Honolulu confused. And they've actually put up a decent amount of new single families and townhomes in ewa beach in the last couple of years. Some in kapolei too. Which has made the traffic even worse.
