Hmm, I guess I never checked satellite for that example. Part of the motivation there was improving the simulation. While vehicles are moving through the intersection, they grab a lock and prevent conflicting movements. A huge intersection takes longer to cross and was causing unrealistic backups here. But that was only because of the wacky lane-changing model (can only change between those 4 northbound lanes in an intersection, where conflicts are modeled) and poor lane placement at the time. Some of that's been fixed, worth revisiting the shape.
