I think the effect is interesting as is the color. The flair doesn't bother me so much- in fact, it looks more "street" to me because of this. I think it would have been better to get a wider gamut of exposures though. Getting 10 exposures would have allowed a greater amount of detail in the police lights and some of the car lights.
I think you were on the side of the road with your tripod and the cop pulled up to tell you to move on,, basically, neat shot though
