349. Lead Vehicle with Adjacent Vehicle evaluation scenario
In the lead_vehicle_with_adjacent_vehicle evaluation scenario, the Ego is driving in one lane of the road with a lead vehicle ahead of it and an adjacent vehicle in the adjacent lane. The scenario designed to detect a potential cut-in of the adjacent vehicle. This scenario does not match if the Ego is driving in a junction.

349.2 Scenario phases
The phase descriptions are as follows:
349.2.1 lead_vehicle_with_adjacent_vehicle
Ego: The Ego drives in one lane.
vehicle_actor: The vehicle_actor drives ahead of the Ego in the same lane, at a distance between
minimal_longitudinal_distance_from_lead_vehicle and maximal_longitudinal_distance_from_lead_vehicle.
adjacent_vehicle: The adjacent_vehicle drives in the lane adjacent to the Ego and the vehicle_actor, at a distance between
minimal_longitudinal_distance_from_adjacent_vehicle and maximal_longitudinal_distance_from_adjacent_vehicle.
