Could you post the links to both of them, then they can be compared...
Free and freezing’s link shows the car hitting people in reverse. Believe this link doesn’t show it. Nathan states that the video doesn’t show what the eyewitnesses said they saw, the car hitting more people when it goes into reverse. So I believe this is one of the videos showing the Challenger not hitting people in reverse. Been watching a lot of videos though to put this together, so not completely sure where I saw what. Viewers of this video not seeing the car hit people in reverse:
18:54 of the Lift the veil video the car in reverse hits people, 19:06 of the video the car doesn’t hit people while in reverse.
