I saw someone doing the idea of placing roundabouts and little "service centres" between the 2 lanes of a highway. So I was trying this myself. One of the experiments was the grade of road used to make the roundabout. When I used the 3 lane highway grade for the roundabout, none of my services knew how to route to an adjacent area - so everyone complaining about garbage but 0 garbage trucks in use. I changed the road grade to a 2 lane road and suddenly the garbage trucks left the service building and started doing their thing.
So is there a bunch of subtle rules about different road grades and what can happen with them? I've not seen any mention of this before, but I'm pretty sure what I saw makes this the only explanation. I'd be interested to hear what others have discovered.
