I agree Terrence..Sometimes luck is all a photographer has. What happens in front of them and what they can get on film. I've read tho that professional photographers know there cameras and lighting so well from experience if anything lucky happens they can operate their cameras, buttons ya know, and lighting available just by feel. I hope to know my camera and lighting situations that well myself someday.
The event was the truck driving through, id metered and set for the ambient light (which was just about nothing, i could barely see anything myself), then the truck goes through, and i realize it must have been meant to happen as otherwise i doubt the road would have recieved any exposure, and no cool light trails, hehe. I depend on luck~
