What it is
A playable Three.js driving simulator where Jev chooses among candidate paths and speeds while local code handles vehicle dynamics and geometry. For developers exploring AI-driven driving decisions.
How it uses Jev
Jev receives compact tables of eligible paths, road boundaries, traffic, signals, stop memory, and destination guidance. It selects a steering-and-speed combination from sampled candidates. The result is used to control the vehicle, with local safety brakes handling collision risks.
Primitives:choice
Technique worth stealing
Send shared table values once and include only relevant situations in instructions.
Try it
npm ci; cp .env.example .env; set TYPESAFE_API_KEY; npm run dev; open localhost:5173
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
