Stanford Roundabouts

The above link is to a web page that Stanford University authored regarding their rationale for installing roundabouts on campus and what they have learned since then regarding the improved traffic safety is for campus residents and class commuters.
I was driving for Uber when in 2014 when Stanford University began installing six roundabouts which are still fully operational on the main campus today. It seems that many ignorant debaters will have a biased argumentative misconception that these roundabouts are confusing circles of accidental death, but Stanford views them as true "Circles of Life." The facts are on this web page, and in simple to understand terms, once installed for use, they are better! Why can't we have this at more intersections?
Stanford found that these roundabouts have fewer conflict points compared to traditional intersections, and are relatively intuitive by design.
And, in their research of traffic data they found the following:
On a national level, roundabouts reduced injury crashes by 75 percent at intersections where stop signs or traffic 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 (FHWA) have shown that roundabouts typically achieve the following:
37% reduction in overall collisions
75% reduction in injury collisions
90% reduction in fatality collisions
40% reduction in pedestrian collisions
To me, there is no doubt that this is the best solution for our troubled intersections. The question is how do we make it happen?
