Traffic jam generator for Blender (Geometry Nodes)

Blender 3.1 required! Can be used in Blender 3.0 if the "Scene time" nodes are replaced by a frame number driver.

This is a Geometry nodes system that can generate traffic jams without any needs for simulation, with an unlimited number of cars and lanes, and with customizable speed and "flow" of traffic. The wheels turn too!

Included is a file with the node tree. Demo scenes will be added very soon.
