So it appears that it's a no brainer for new construction because they have to be cheaper than a four way stop light. Why aren't we building more or these?

Roundabouts reduced injury crashes by 75 percent at intersections where stop signs or signals were previously used for traffic control, according to a study by the Insurance Institute for Highway Safety (IIHS). Studies by the IIHS and Federal Highway Administration have shown that roundabouts typically achieve:
A 37 percent reduction in overall collisions
A 75 percent reduction in injury collisions
A 90 percent reduction in fatality collisions
A 40 percent reduction in pedestrian collisions
