DrivingBench Harness v1
The harness behind DrivingBench v1: AI models drive a comma-equipped Toyota at parking-lot speed through three MCP tools (observe, set_motion, stop_now), with a supervising driver at the wheel.
- One MCP server,
drivingbench_sandbox, for Codex, Claude Code and Cursor. - A native 100 Hz controller inside openpilot v0.11.2 (two modified files) that turns timed steering-percent commands into openpilot's own curvature and longitudinal control, under openpilot's and the car's limits.
- A laptop gateway with Setup, Drive and trace-viewer pages, and every tool call, image and 100 ms of telemetry recorded as replayable traces.
