So, will the number of headers equal or exceed the number of t-bones that were prevented by the DDI?
I share your impression and your question. The first time I encountered this in St. Louis it was nightime with fog and it was truly disorienting.

I noticed the same, especially at night.

With traditional overpasses, there's a fair chance you pass over the freeway without having to stop.
Concur.

Also concur

Oh, that would be much worse from my perspective. I detest traffic circles.
