Unironically just show up to court. I've had to pay less than 30% of parking tickets acquired as a result of showing up each and every time. When they do show up, I usually pay a small fraction of the initial fine after being polite to the cop.
I used to do this, but now I lose more money missing work to go to court than the cost of the ticket so I just pay for parking upfront to avoid the whole hassle.
