Thank you for your answer, i changed the road segement to 5Km but it did not help, i made a traci call to make an urgent lane change for vehicle 2 and what i noticed is that when i put vehicle 3 in speed mode then 2 waits for 3 to pass and then 2 changes to the middle lane, however if i have 3 in cooperative(or default) vehicle 3 changes to the top lane and leaves the middle empty for 2 and if both 2 and 3 are in cooperative vehicle 3 goes to the bottom lane and 2 in the middle.
