I suggest keeping your camera on at all times while riding, even at night. After your next ride in the dark, watch some of the footage and see if you can read any license plates of cars around you. Sometimes your headlight will provide just enough light to read the license plate.
What I do is loudly recite the license plate number of the car, so the audio may pick it up even if video does not. I also do that if a driver is being aggressive, along with an audible observation that the miscreant is being filmed and that the footage may be turned over to the authorities.
