Jesse (or Rex) is sat, leaning right down with his head level with the bike's windshield and turns his head (right) to face the camera! (Just before the headlamp pops up).
I guess most people have already realised that but I ALWAYS thought that the helmet was resting on the bike and, kind of, turned/twisted toward the camera as Jesse grabbed it from up and under it's rear. I think maybe, because that early sequence is so dark, with quick edits, it was hard to see what was happening in certain bits.
Also, I gotta say, I find that little edit somewhat unnerving or creepy. A still, opaque helmet turning slowly (robotically even) to face you.
And that's all I got to say!
