To reduce risks, it’s crucial to identify the ADF’s potential failure modes and establish appropriate mitigation strategies. Fail operational strategies should be employed whenever feasible, allowing the ADF to maintain control over the driving task for a certain duration without necessitating an emergency handover. The need for such handover maneuvers introduces substantial risks, as they limit the time available for the driver to regain essential situational awareness. Various mitigation strategies may be available to address individual failure modes. These should be evaluated and prioritized based on their effectiveness.

Main Question
Are the potential ADF failure modes due to interaction with mixed traffic identified within the ODD and have relevant failure mitigation strategies been implemented?
Sub-Questions
- Are potential failure mitigation strategies considered, including both fail operational and fail-safe techniques?
- Is the limited capability of the ADF considered, based on the mitigation strategies selected?
- Is setting a hierarchy of mitigation strategies considered, depending on its impact and effectiveness?
- Is there a safety concept for cooperation between the ego vehicle and other road users?
