I think it’s safe to say that the intersection object (that is not really an object) and the wizard that creates them are from a different age, they are dinosaurs that should have died a long time ago.
Check out 12D’s “Create Roads” functionality. It creates “multiple intersections” at once, as well as creating the cul-de-sacs automatically. Why can’t civil 3d leave the dark ages and develop some functionality like this?
