According to the responses on the thread so far, it was the owner’s fault that the dog attacked him while he was driving his car.
The dog was merely trying to correct either the master’s tone of voice, or his choice of music.
I’m going with Joe’s cheeseburger theory.
No, I don't think so.
But they are noting that we don't know all the facts. And some of us are pointing out that there are a lot of things that can set (any) dog off. That's why so many people are crappy dog owners, they don't try to learn what those things are for their dog. These people may have done nothing deliberately to set this dog off, so it wouldn't be their "fault" in that sense. But it's a pretty good bet that they knew a great deal less about their dog & dogs in general than a responsible dog owner should. I can safely say that because it applies to the majority of dog owners.
