I have a similar story with a different ending. I allegedly made a right turn on red without stopping. That's running a red light. My car was on video, which I could watch online. The front bumper of the car allegedly crossed the white line 400 milliseconds after the light turned red.
I paid an attorney $300. He took all the standard legal means to delay the trial so that if he lost, the ticket wouldn't affect my insurance until the next year, thereby delaying a price increase. He wound up getting me an acquittal because the driver (allegedly me) was wearing sunglasses. The judge accepted his argument that, due to the sunglasses obscuring my eyes, the city could not conclusively determine that I was the driver.
