Create a sceanrio for same velocity and distance

HI all I am trying to create a scenario where I want same speed for both target vehicle and ego vehicle. Also through out the scenario it should drive at same disance but in my case target vehicle is moving very fast. can someone guide me to make it possible?

Good morning,

you should set the manoeuvre in the traffic object at a speed identical to your ego vehicle (IPG driver settings) and also similar longitudinal motion parameters in the autonomous driving tab of the traffic object such us maximum longitudinal , deceleration and lateral accelerations.
