Good luck with that.

Going by similar things I see where I live, I don’t see how diverging diamond works in practice, even if the theory is good.

The problem is

• it’s unfamiliar to drivers
• drivers see a huge expanse of pavement with insufficient indication where to go. I see people all the time accidentally cross lanes
• since it’s a very shallow angle, it’s all too easy to get confused and accidentally cross over into oncoming traffic
• cities never keep up with road maintenance. Lane lines are critical here, but once they are worn off it’s just a free for all
• there’s always more traffic. It’ll quickly back through the intersections and cause gridlock, yet it’s not easy for drivers to tell when they are even in the intersection
