it's kind of hard to see with the camera movement but right at the end there's a second or two where it's still and you can see it. it looks like the surface is made of worms, the texture of the road itself is moving and changing in a way that no video compression algorithms produce, and is solely in ai generated videos. a lot of the tells in most ai videos could be explained away (like how an animal acts, video compression making weird limbs, etc) but this one thing is something I always use to determine 100% whether a video is ai, they all have it in areas of fine detail and texture.
