Checking out the video, looks like the dude was holding his face right down by the exhaust pipe.
If the vehicle was running perhaps that's why he couldn't breathe and what really killed him, breathing car exhaust for 7-8 minutes.?
It would be hard to asphyxiate someone with modern car exhaust outdoors. Modern vehicles just run too clean anymore. I saw a few of those early in my career, and none at all at the end in 2013.
Fight fire, save lives, laugh in the face of danger.
