I am the long-time critic of the roundabouts (e.g. traffic circles) that San Diego is placing at intersections across the city. The euphemism for them is “traffic calming”, by official parlance. I call them danger zones—directly when you go through them and indirectly how they negatively change driving behavior.
The Featured Image and companion are evidence of the first. Two SUVs collided in what looks like one driver failing to yield to another already in the circle. This kind of confusion happens frequently.
Changing behavior is more insidious—and dangerous! Many drivers no longer stop at Stop signs. They roll through like they would the traffic circle. As such, at least in my neighborhood of University Heights, accidents and near misses occur more frequently than before the roundabouts arrived. That conclusion is based on my anecdotal observations.
