The race demo's drivetrain is a real electric motor curve — constant torque off the line, constant power above base speed — not an arcade throttle.

The race circuit isn't a mesh or a hand-built spline — it's ten waypoints, per-corner fillet radii, and an arc-length sampler.

The crash rule is one formula — v_max = √(μ·g·r) evaluated against the track's sampled curvature. Exceed it and you're off the road.

The demo drives itself. No path planning, no learned policy — a proportional controller on heading error plus a look-ahead brake.

Side note on the race audio — a CC0 Bach recording, a gain-capped WebAudio chain, and a pitch-class visualizer using the equal-temperament ratio.
