It’s less suicidal than trying to make a left turn on a busy highway. I generally turn right then make a u turn at first opportunity. It takes less time than waiting for traffic to be clear from both directions for a left turn.
I think it is just to save money on an overpass. Having trouble remembering the term for the cost of project vs. human life
I just returned from Florida and while there I was wondering, why everyone was making U-turns. Here in North Carolina we still have the suicidal four lane island intersections. This will take a lot of re-education in N.C. We had three new traffic circles ten years ago in our county and people still can’t figure them out. The first month it was like the Dukes of Hazard. They had to launch a public education campaign. I would miss the excitement of crossing three lanes of 70 mph just to find my median blocked by a horse trailer. It is a smart idea. It will take awhile for the people here in western NC to get it. Our drivers can’t figure out a four way stop intersection or a bicycle lane, plus most are over eighty and heavily medicated.
