I bet people who use grid road layouts will find this especially helpful. Althoug I kind of like it that highways aren't always exactly perfect; reminds me of some sections of highways in RL. However, I like having another tool in the tool belt, so to speak. I made ground-level and raised highway roundabouts in the asset editor for the exact same reason: did not want to keep trying to re-create it every time I needed one. Thanks for the mod.
