Audio problem: When Walter is destroying the expensive sports car, the owner comes out of his house to stop him. You hear him screaming, but his mouth is not moving. (01:12:40)
Audio problem: When the Malibu Police Chief throws his coffee mug at The Dude you hear it glance off his forehead but never hear it hit the floor. Even if it somehow didn't break, it's a solid floor (not carpeted) so the impact would've made a noise.
Chosen answer: There's no way of knowing. If the hiker was that far away, it could have been someone who happened to stray into the scene by accident. The filmmakers may or may not have noticed, but if they did, may have felt it added to the realism. I did this myself during the filming of a street scene for the TV show, "Northern Exposure." Filming was underway before I realised I was in the midst of it. I just kept walking like I was supposed to be there.
