- Tesla's latest iOS app update contains code for a new driver identity verification feature using the cabin camera to allow Full Self-Driving activation.
- If the camera fails to match the driver to an authorized profile, FSD will be blocked with an error message shown in the app.
- The code was discovered in version 4.58.5 via decompilation and includes strings like 'fsdIdentityCheckFailedTitle' describing the flow.
- This is not yet a shipped feature and would require a corresponding vehicle firmware update to go live.
- Tesla has been using the cabin camera for driver monitoring since 2021, evolving from attention checks to identity verification.
- Identity verification serves as a permission gate, distinct from attention monitoring, to control access to FSD based on authorized profiles.
- The feature aims to restrict FSD access to account holders, useful for rentals, shared vehicles, and preventing unauthorized use by teens.
- It also supports Tesla's Robotaxi ambitions by matching riders to booked rides using the cabin camera.
- Limitations include the camera being a standard RGB sensor, not infrared like Face ID, making it less secure and susceptible to lighting, obstructions, or sunglasses.
