Car Traffic Generator adds AI-driven cars to a world, so roads fill with vehicles that drive on their own.

What it does

Car Traffic Generator is distributed as a data pack that places AI cars into a world. Worlds created with the current build can use the mod version, while a world that should get only the traffic from a fixed set can stay with the datapack version. The server needs the mod, while players may join without installing it. Builds cover 1.17 – 1.21.4 across Fabric, Forge, NeoForge and Quilt, and the code is released under the MIT License as open source.

Key features

AI cars
The data pack spawns cars that move through the world without any player control.
Mod or datapack version
Worlds made with the current release can run the mod build, while older or selected worlds can keep the datapack version.

Questions

Does the server need Car Traffic Generator?

Yes. The server is required, and the client may leave the mod out.

When should a world use the datapack version?

The author suggests the datapack version for worlds that should keep only the chosen traffic, while newer worlds can use the mod build.
