The guy refused eye contact at all costs to escape bear. His reaction was picture perfect. A cub means mama is nearby. By standing still and making no sudden movements or attempting to run or interact with the cub, it shows he is not a threat. You'll notice at the 0:36 mark, he actually gives a thumbs up to the person in the car. He was fully aware of the cub the entire time; he notices it right at the beginning when he turns his head. You see him go from relaxed to vigilant pretty much right away. When the cub began jumping on him, he had to make a decision; if a cub is jumping on you, regardless of if it's curiosity or as a predatory behavior, that's all the green light mama needs to tear you apart. And looking away, avoiding eye contact and keeping your arms as close to your body as possible is exactly the recommended course of action. You can see perfectly well that it works – even the bear doesn’t know what to make of him as long as he stands there still, with the bear just ‘nibbling’ at him in confusion. But as soon as he moves again, the bear starts chasing after him once more. So this bloke knows about what to do in this situation. He is so remarkably calm even when the bear nibbles his leg.
