We need this in SF. SFMTA ticketed my car for no reason before; I tried their "appeal" process, only to get a response that sounded like they didn't even read what I said.
Huh. I appealed a parking ticket in SF one time and it was dismissed. I got a street cleaning ticket that said I parked on a Tuesday but the address on the ticket was on the Thursday street cleaning side. Just pointed that out in a letter and everything was dropped. However, my scenario is pretty straightforward. I'm guessing anything more complex is going to get denied. You can always appear in front of a judge.
The problem is that regardless of how angry petty bullshit injustices like this make me, it is simply not worth my time to go fight a parking ticket (it was like $100 or something) in person. Same thing for hiring a lawyer -- it's cheaper to just pay. Plus, I imagine they have the final word anyway and I'm quite disillusioned with the fairness of their whole "trial" thing.
I suspect this is the case for many/most people who get these tickets, and probably a large part of the reason that they can get away with it. It's disgusting but true, and besides someone exposing the scam with data like this, I'm not sure what else I could've done.
