Justin Schroeder rebuilt Tesla Full Self Driving as a playable Three.js simulator, with Jev picking the path, in less than an hour. The model sees compact tables of candidate steering-and-speed paths, not pixels, and answers up to four times a second near traffic. The repository is open, and a hosted build is at jevpilot.standardagents.ai.

The simulator samples fresh steering-and-speed combinations for each decision, filters out the ones that leave the road or collide, and sends Jev compact tables of the eligible paths, road boundaries, nearby traffic, signals and destination guidance. Detailed geometry and control stay in the browser. Questions with only one eligible answer are resolved locally, and a safety brake in code handles imminent collisions.

Requests run up to four times a second near turns or traffic, and about 1.5 times a second on clear roads. The J key toggles autopilot. A hosted demo at jevpilot.standardagents.ai signs you in through Standard Agents and meters $0.25 of Jev credit on the server, so the API key never reaches the browser.
