The light trail by the gray car is a light, not the spectral reflection - as you point out, none of the others show that. This isn't "camera movement" the way we usually talk abou it -- this is opening the shutter for a long exposure, then picking up the tripod and walking away just before the shutter closes. (Or taking the camera off the tripod.) Looks like there was some twisting motion, too, as the trails on the bottom left are more circular than those on the top right.
