My experience with roundabouts is they work wonderfully in some places, and horribly in others. I feel like at least where I am, because they work so perfectly and elegantly in certain situations, better than other solutions, they then get overapplied, in situations where they are horrible. It's a variant of the "when you only have a hammer" analogy: when you first learn how great a hammer can be, everything looks like a nail.
