Episode summary

This episode is a deep dive into one of the rebuild’s hardest problems: making vehicles work reliably in dense, living cities. Robert and Derek walk through the current state of the Ajax, breaking down why vehicle AI is so difficult at scale and what’s actively being done to fix it. From higher-speed handling and smarter braking to predictive turn logic, obstacle detection “antennas,” and road-preferred navigation, the team shows exactly how vehicles decide where to go—and where that logic still breaks down.They demonstrate new physics interactions like snapping streetlights, destructible roadside objects, and weight-based ramming that lets vehicles plow through infected while gradually losing momentum. At the same time, they’re wrestling with edge cases: lamp posts that attract collisions, formations that force vehicles into bad decisions, early turns that cause crashes, and tight navmesh margins that leave no room for error. A major takeaway is that rotation-in-place and smarter recovery behaviors—common RTS cheats—are likely necessary to make vehicles feel dependable rather than babysat.Beyond vehicles, the episode covers parallel AI work. Infected now use squad-based logic to reduce conga lines, spread attacks, and lower CPU cost, though target fixation and corner clustering still need refinement. Building-avoidance nav layers are being added to stop hordes from hugging walls, while performance hitches tied to nav rebuilds and async checks are under investigation.The team also previews upcoming systems: weight-class destruction (fences, walls, street furniture), juggernaut interactions, convoy formations with infantry, and how all of this groundwork feeds future features like civilian evacuation buses. On the content side, Robert shows progress on new infected meshes, plans for expanded civilian/infected variants (police, firefighters, National Guard), and explains why fully modular clothing systems aren’t feasible at the game’s scale.The episode closes with roadmap clarity: vehicles won’t ship until they’re reliable, even if it takes another week; playtests will run daily to hunt failure cases; and December is shaping up to be a heavy month with vehicles, doctrines, operator polish, and major systemic fixes landing as the rebuild pushes toward its one-year milestone.
