LOL, I don't know why, but I completely imagined a Gary Larson "Far Side" cartoon, where a tiger, follow some bushmen in the tall grass, suddenly realizes they are masks and thinks to himself:

"Hey! What kind of cruel trick is this?"

LOL Yep, those masks do have a Far Side bent to them. A little surreal.

Apparently they work very well. But not 100%.

The best bet for the two bikers in this story would have been to stick together, side-by-side/back-to-back, and fight. Sad but you’re right about atavistic instincts taking over.
