The Hwy 17 access to Surrey is traffic light intersections with a speed limit of 50km/h for those zones. East of there the speed is signed 80km/h or, I think, 60km/h and the game recognizes that correctly, but the AI traffic still keeps the 50km/h speed limit and makes it a painful road to drive on.
I currently don't have coordinates, but the area in question is within this outline anywhere a speed limit is entered higher than 50:
