Wonderful use of a long shutter speed (or perhaps rear curtain flash sync.) Exposure, composition and focus spot on. Minor problems are the whit dot in front of the pants and at the top of the accelerator. Black border is pretty "heavy."
I really liked the way this is put together. I certainly feel the "hesitation/choice" of putting the brake on. I hope you were parked when you took this!
I think the slow shutter speed has been utilized really well for this subject. It doesn't just look like a single motion. It could easily represent indecision or a number of movements.
