Hi,
I actually can not control when it happens and how much it happens. The video in the main post and the last video are recorded on the same road. The cars are spawned by the same starting point.
In the first video, dislocation of the red car happened near (-6610, -15000, z of road) and I put a traffic sign by the road, which you can see in the beginning of the second video.
I will try to relocate this road to pass world center and see how it works.
