The camera is apparently mounted on the handlbars, fixed forward like the headlamp. He (or she) had to turn the bars to the right to get the bike to tip to the left to begin the U-turn on the trail, then bars hard left to make the turn. The magnification is probably centered in the frame and so swings with amplification wherever that front wheel is pointing, not at the critter.

My reaction, I think, would not be to turn tail, but rather to stop. Then creep forward to have a better look.

I'm not known for bravery, but I'm also not known for being too swift upstairs.

I too vote for "staged".
