Originally, terrain editing was click based. However, I noticed that clicking like a hundred times to make a hill is rather inconvenient. So now there's continuous terrain editing.

The solution: Pin the front wheel's center position to the path and use the Kinematic Bicycle Model to update the rear: thomasfermi.github.io/Algorithms-f...

Integrated the 2D traffic simulation into the 3D world. Got it working on first try.

Added some car state visualization for debugging.

There are 10,000 cars in a simulation area of 10km² ≈ 4mi²

Added some simple car-to-car interaction and traffic lights

All cars spawn randomly but with the same target location.

The catch: Each car can only query roads nearby so only partial A* calculations are possible. I do this to simulate a chunked world where chunks can be missing at spawn time. As a result it may produce suboptimal paths

Sometimes it's surprisingly useful to work on an aspect of the game isolated from the rest of the world. Here, have some traffic simulation.
