Windows 10 (64 bit)

Location: North Las Vegas where I-15 N exits onto route 93 North (exit 64) (and many more not shown in this example)

Description: Lane change SOP (attached) specifies that the rear escort should lead the lane change maneuver, followed by the forward escort, yet I never see this. This report depicts one such example of this failure.

Evidence: Seven snap shots are recorded in one Imgur post

1. Lane change SOP
2. Map
3. Lane change warning announced
4. Forward escort starts lane change
5. Rear Escort did not change lanes first
6. Forward escort completes lane change first
7. Rear Escort continues to follow player
