Hello. This afternoon I player some time to AMS2 and I found a bug when I saw the replay. As you can see in the video at the bottom, the feets of the Puma GTE drivers can be seen outside the car, under the car floor (it seems like the Flintstones ):
As @KRoman47 and Reiza have said, the drivers are placeholders and have not yet been manipulated to their 'starting positions' for each car as of yet.
