Is that U2 song the new official slow motion lfs video theme?
Anyways, I dont know if it was my player or youtube but there seemed to be a lot of stuttering. Also, imo, a slowmotion video is to show off the suspension while its working. You have none of that, so it just seemed you drove really slow.
Try going over some more bumps and take turns, so the weightshifting in the vehicle is more noticable
