"Although roundabouts typically require more area at the junction
compared to conventional intersections, they may not need as
much area on the approaches."
"...flared roundabouts offer the most potential for
reducing spatial requirements on the approaches as compared to conventional intersections. This effect of providing capacity at the intersections while reducing lane requirements between intersections, known as “wide nodes and narrow roads...”
I'll say it for the last time: Roundabouts are a traffic control tool. You use the tool that works for the specific job. Just because a hammer can drive a nail in wood doesn't mean it's best for gluing paper, and a glue stick isn't the best tool for pounding a nail.
Did you see the movie “My Big Fat Greek Wedding”? I think roundabouts is your Windex…..
Are roundabouts workable in Puna? Who the heck knows until a comprehensive review is conducted. Since I have not done any review I can't say they will or won't work. But it appears you have.

So Bob, seriously,
Have you shown your traffic engineer a map of Puna? I would sure be interested in hearing a professional opinion.
