Two proper venues off the real Ipswich pair, both built in code. Willowbank Dragway (levels/willowbank_dragway): a true 402 m dual-lane strip -- concrete launch pad, FLUX-rubbered lanes, crowd grandstand with canopy, red control tower, distance boards at 60ft/eighth/1000ft, checkered finish under a scoreboard gantry, sand trap and tyre wall, smashable SL_ light towers and a staging paddock of parked fleet cars. Between the lanes: a working christmas tree, six bulbs driven by game.gd through material_override emission. Drag mode grew the event around it. Every drag now stages at the tree (three ambers, green at 2.7 s); rolling >2 m early is a RED LIGHT that bogs your launch. The opposition is a six-rung ladder of preset locals (Nanna's Shopping Run through The Willowbank Widowmaker), each with its own fleet car, power and reaction time. Beating your current rung climbs the ladder and pays an escalating purse ($250-$1600, top dog repeats); crossing at all pays $50; and every car keeps a persistent quarter-mile PB worth $150 when beaten. Losing no longer ends the run early -- you still cross for your ET, with a 10 s grace if you dawdle. Ladder rung and PBs persist in the garage save (schema extended compatibly). Queensland Raceway (levels/qld_raceway): the National Circuit digitised from the official track map and scaled to its exact 3126 m lap. The road is one generated quad strip with trimesh collision; kerbs, gravel traps and tyre stacks derive automatically from centreline curvature, sponsor hoardings space themselves down the straights, and the SF straight gets the checkered line, gantry, pit wall and the mandatory red pit complex. Plus the pond. Race/cruise/rage all run on its RacePath. Trap for the diary: Godot front faces wind CLOCKWISE. The first cut of the road ribbon wound CCW and rendered invisible from above while colliding perfectly -- the smoke suite passed and the screenshot showed four cars gridded on open grass. Three new FLUX textures (crowd, dragstrip, sand; the sand prompt tripped Cloudflare's NSFW filter, of all things, and fell back to local). Smoke suite covers tree staging, the held rival, rung-0 identity, green-bulb emission, red-light innocence, PB/rung persistence and the 3126 m lap. Also swept stale shot_*.png.import debris and ignored the pattern. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

## Willowbank-ish quarter mile, built in code like the carpark. A real 402 m of
|
|
## strip plus shutdown, sand trap and tyre wall, with a working christmas tree
|
|
## (game.gd drives the bulbs via their material_override emission).
|
|
##
|
|
## Geometry contract with game.gd's drag mode: DragStart sits at (0,0,0) in the
|
|
## .tscn and DragEnd at (0,0,-402); the player spawns at x=-2, the rival at
|
|
## x=+2, both facing -Z. The tree stands between the lanes at z=-6, visual only
|
|
## -- collision there would turn a wandering launch into a head-on with a pole.
