127. Vehicle Lane Hugger Right evaluation scenario
In the vehicle_lane_hugger_right evaluation scenario, a vehicle (vehicle_actor) that is driving in the right lane adjacent to the Ego and is hugging the lane line. The scenario involves both vehicles driving in parallel, with vehicle_actor maintaining a close lateral distance to the lane's left boundary.

127.2 Scenario phases
The phase descriptions are as follows:
127.2.1 vehicle_lane_hugger
Ego: The Ego drives in one lane and maintains its lane.
vehicle_actor: The vehicle drives in the right lane adjacent to the Ego vehicle and is hugging the lane line. vehicle_actor maintains a close lateral distance to the line on its left side and a longitudinal distance between a minimum of min_longitudinal_distance and a maximum of max_longitudinal_distance from the Ego.
