361. Vehicle Cut Out Exposing Vehicle Scenario evaluation scenario
In the vehicle_cut_out_exposing_vehicle evaluation scenario, the vehicle_actor drives ahead of the Ego in the same lane, with the Ego following behind. The vehicle_actor then changes lanes, revealing the exposed_actor which is also driving in the Ego’s lane.

361.2 Scenario phases
The phase descriptions are as follows:
361.2.1 initial_phase
Ego: The Ego is driving in the same lane as the vehicle_actor, following behind it.
vehicle_actor: The vehicle_actor drives ahead of the Ego in the same lane and remains close to the Ego
at a distance between min_distance_from_sut_in_time_units and max_distance_from_sut_in_time_units.
exposed_actor: The exposed_actor drives in the same lane as the Ego and the vehicle_actor, ahead of the vehicle_actor.
361.2.2 cut_out_phase
Ego: The Ego continues driving in the same lane.
vehicle_actor: The vehicle_actor drives in a lane adjacent to the Ego, revealing the exposed_actor to the Ego.
361.2.3 post_cut_out_phase
Ego: The Ego drives behind the exposed_actor in the same lane.
exposed_actor: The vehicle_actor drives ahead of the Ego in the same lane and remains close to the Ego
at a distance between min_distance_from_sut_in_time_units and max_distance_from_sut_in_time_units.
