Yep it's also drifting to its right and does not scale correctly with distance. Clearly an attempt was made but the result falls short. Protip for whoever made this: after recording the main shot of the road, put an object (a box for instance) with known dimensions in the center of the shot, then replicate that object in your 3d scene. You can then use that to properly align your models with the video. For best results you can also put known objects at known distances in both the foreground and background to assist with matching the lens distortion of your virtual camera to the real one.
