Solved the "reactive crowd" challenge by layering multiple detection systems: clothing affiliation (±60% detection), vehicle context, combat history, and social norms. NPCs now actually see what you're doing - addressing the immersion break that happens when open-world crowds ignore player actions.

Addressed the "silent protagonist" problem by making V actually respond to world events using unused voice lines already in the game files. Built an escalation system so reactions intensify naturally - light bumps get grunts, repeated harassment gets the finger. Turns player character from passive camera into someone who exists in Night City.

Architected a universal vehicle boost system that automatically supports 100+ vanilla and modded vehicles with zero configuration. Built proper game state integration including exhaust VFX on existing hardpoints, designed immersive HUD widgets, and exposed a full tuning API via tweak records.
