I have used roundabouts mainly in Europe and on just a few occasions in the USA. I think the advantages outweigh the disadvantages, but my main reason for supporting them in Puna is simply the fact that they are outside the box of the typical Hawaii DOT cookie cutter approach to highway engineering. The fact that they are not part of the "let's multi-lane everything and do it like we did in Honolulu" attitude of the DOT is enough to make me want to give it a try. Perverse reasoning, perhaps, but it works for me.
