Got a witness to contact the other guy's insurance. Starting to look like insurance might cave, but they are sending a guy out to time the lights at the intersection.
Here is my one regret: I didn't get the guy's current address off of his driver's license. If I had, I would feel it was very easy to sue the guy in small claims court. Right now it would be a pain to serve him process... I would need to call him and demand his address or that we meet in person to serve him or else ask for some kind of relief from the courts if he is evading process service.
