Driving down Lombard Street
Author’s claim. Posted before Fable 5.2 came out. The author called it Fable 5.5, the name rumors gave the next Fable. We can’t verify which model ran.
A driving simulation of a Waymo-style car winding down San Francisco's Lombard Street, with a playable browser demo. The author says it was built with Three.js.

Our note
A chase-camera drive behind a white car with a roof sensor rig, starting on the flower-lined switchbacks of Lombard Street and carrying on through flatter blocks of painted Victorian houses and palm trees. The HUD reads like a robotaxi app: a minimap at bottom left, a speed dial that tops out around 103, and a trip card with the destination and a $10.50 fare. Traffic and pedestrians are sparse. It looks like a browser 3D scene, and the author says there is a playable demo. We have not played it. No prompt was shared.
