Arav Srinivas detailed a major update to SF 2049, the AI-built browser game: it's now multiplayer, with race rooms on Cloudflare Durable Objects (six-letter room codes, server-side lap timing), 10 new player cars generated via image-to-3D, a Blade Runner-style flying Spinner, Rapier vehicle physics with handbrake powerslides, and a map faithful to San Francisco's real street layout. The trailer was shot by three agents in parallel. Chris Albon quipped that 'SF 2049' sounds like a ballot measure he might have voted on.
