Problem Description
A navigation simulator controls an autonomous car that endlessly travels between two points: A and B.
The system claims this route is fixed and secure.
However, deeper inspection shows the car’s behavior depends on hidden backend logic, session state, and timing constraints.
Your mission is to hack the simulator and force the car to complete the following exact journey:
A → B → C → D → A
The challenge is progressive:
Each successful step unlocks new restrictions
The user interface does not expose all functionality
Incorrect actions may soft-lock your session
You must discover undocumented endpoints, manipulate server-side state, and exploit timing flaws to succeed.
