IF Feedback to LRM: Multiple controllers for same object at example of ELK Overtaking scenario

Feedback from @matthias.bueker from a presentation in the Simulation and Execution Group

This feedback originates from the scenario ELK Overtaking that was investigated in the IF.

• How to specify a scenario with an action that is expected to be overwritten / prevented by the intervention of an ADAS SUT?
  • In this case the driver of the SUT-car leaves his lane and gets into the danger of colliding with an adjacent vehicle. The expected behavior of the ADAS SUT is to intervene in time to prevent an accident.
  • When trying to specify this scenario the question arises whether to specify the trajectory the driver would drive without any intervention of the ADAS SUT (like depicted in the regulation) or to specify the trajectory that is to be expected taking the ADAS intervention into consideration.
  • However, the latter is more something like the expected outcome of a test i.e. a kind of pass/fail criterion
  • This issue has also tight relations to the question how to treat scenarios where different entities might control the same vehicle (which has already been raised somewhere else)
  • As this seems a very relevant point in practice (like the reference EURO NCAP regulation), we should try to give an answer whether, how and when this is approached by OpenScenario 2.X

Comment: Not sure whether this is more language or more domain model (or both)
