This seems a lot more like blurred motion than abstract. I've been using the definition: "Of, relating to, or being a style of art in which natural objects are not represented realistically."
I've rated this a 10 because of it's simplicity, clean lines and the effective way it works within the rules of the Challenge. It may not be the technical best ever, but it really hits the Challenge rules dead on.
One of the more interesting images of this genre ... the illumination of the posts supporting the railing on the upper roadway and the partially illuminated road surface next to them are nice details. I also like the way the pillars supporting the upper roadway, as well as the upper roadway itself, break up the lights on the lower roadway. Nice image.
I have seen many traffic motion shots before, but this is the first that I have seen that incorporates an overpass. I like the effect, and your red/orange tones stand out nicely. The only critique I would have is the bottom left corner. If your tripod was higher, you wouldnt have the fence cutting off part of the light. I doesnt affect how I will score you though. 7
