Composition
You have used the elements here to work very well together. The curve in the road gives 'motion' to the picture, and the simplicity of the shot makes it easy for the eyes to rest on the car. The placement of the car in the lower third of the frame allows for some negative space that helps to add to the tension.
Technique
I like the "fuzziness" of this shot. I think this is an example where something is in focus, but looks soft or blurry. the light bouncing off the top of the car gives the impression of a sunny day, and the presence of fog/mist makes it appear early in the morning. I suspect this was difficult to expose correctly, but you have done a nice job. I think the only suggestion I can give you is that if it had a bit more contrast, it may have had a little more punch or "omph" to it.
Overall Effect
I really liked this shot. It evoked emotion in the viewer (or at least me) by giving a tense feeling. though it is not something I would necessarily display, I can see how it would make a nice shot for a travel brochure or advertisement.
This image really appeals to me, for some reason. Maybe it is the muted colors (which I normally don't care for, oddly enough), or the mysterious feeling that it has. I like it.
