DrivingBench Simulator
The Gaussian splats behind the DrivingBench simulator, a drivable twin of
the v1.1 cone course. They were trained on the Tesla Model 3's own road camera on 27 October 2026,
from frames taken between 15:30 and 17:00. The simulator itself (the course, its cones, the
drivable region and the car fitted to the Tesla's logs) is in the
DrivingBench harness, under sim/.

Both are .splat files (32 bytes per Gaussian: position, scale, colour and opacity, rotation), in
the course frame in metres. The real cones and the haze along the car's path are removed; the
simulator places the course's cones back as objects.
Use
From a checkout of the harness at v1.1:
uvx --from huggingface_hub hf download drivingbench/simulator --repo-type dataset \
--include "*.splat" --local-dir runs/sim/explorer
uv run python -m drivingbench.sim.runtime # the simulator, on 127.0.0.1:8877
uv run python -m drivingbench.sim.explorer.serve # the lot explorer, on 127.0.0.1:8890
The harness's docs/sim.md describes how the splats were built and how faithful the simulator is.
