Great work here, kudos!
This reminds me of the work of a very famous blind photographer who light-paints cars, mostly.
Probably a cliché, but I see/imagine some reflections at that lighted part of the road. Perhaps a few puddles or a full reflective surface would do excellent job. I know it could be done in post-processing but it's not that interesting that way, right? :D
