I find it exciting to see that traffic engineers on both sides of the pond are working with a much richer palette, possibly enabled by public sentiment that has softened on the idea of how intersections "should" be done. At grade, above grade, signalized, corner, or circle; these decisions require a balance of traffic flow, safety, real estate/cost, and aesthetics. To have engineers or local decision makers not consider an option out of unfamiliarity/prejudice is silly.
