I think I'd be inclined to just pay the ticket and move on.
I fought what I considered to be a fairly frivolous ticket a few years ago. I got my Matlock on and went all lawyer and shit in the courtroom. I had diagrams and all kinds of shit. I had what I thought was a great case. My impression is that the judge that heard the case out of the small town where the ticket originated wasn't too pleased with me and my antics and did not rule in my favor. Well, fuck that, I said, and appealed that shit and took my case downtown. Went downtown, long story short, I ended up getting a favorable plea and took it.
Yay, vindication, right? Well, not really. I mean, it was kind of cool to play junior lawyer and all (I was pre-law at one point in college, after all), but in the end I am pretty sure I lost out, considering all the time I had to spend preparing my case and appearing in two different courts on two different days to fight it. And it wasn't like I was charged with vehicular homicide or something crazy like that. In restrospect, my time probably would have been better served by simply paying the ticket and moving along (or paying an actual lawyer to fight the case).
