The new AI will build "war roads" as I understand it, in addition to city connections.
This bit sounds dodgy.
As an example then, why does it want me to build a road south of Philadelphia. There are already roads connecting and going thru the city. I guess it could be a secondary bridge to the east. But it's not really all that helpful since the beachhead on the other side is the same manufactory. It won't really make things faster. The city isn't really a front line city, Egypt is to the North but they are not important. The warzone is like two cities to the south. So all it would do is cost money. It's a road to nowhere or for nothing.
