The full change list of the SimCity 2013 Patch 1.7 can be seen below:
•Traffic Improvements: Tuned traffic congestion and fixed some intersection traffic issues.
•Traffic improvements: Emergency Vehicles will drive in empty lanes to get around traffic at intersections.
•Traffic improvements: Emergency and Delivery vehicles get priority over regular traffic when leaving garage.
•All units and buildings can now be demolished using the bulldoze tool.
•Performance improvements for low spec systems.
•New Server: Asia 2 will be released Tuesday afternoon (PDT)!
We didn’t get a chance to test this patch yet, but hopefully it fixes the huge problem the game had with intersections and pathfinding.
