Issue
Drivers and spectators see different vehicle positions or collision outcomes.
Cause
Custom forces, controller state, or nondeterministic setup are not represented consistently in authoritative simulation.
Fix
Centralize vehicle state transitions, use supported authoritative components, and make input packets describe intent rather than final position. Remove hidden client-only constraints and validate that every client starts from the same vehicle configuration.
Verify
Record driver, passenger, and spectator views during collisions under artificial latency.
