In the latest Dev branch, you can try out new vehicles like the truck.
The side mirrors display interchanged images. The left mirror shows the image from the right mirror and the right mirror shows the image of the left. I attached some images, where you can see the issues.
The next thing is, that the mirrored image is "recorded" from the trunk/rear of the truck and not from the position of the actual mirror position. You can see that issue at the attached pictures too. {F21875} {F21876} {F21877} {F21878}
