The fun answer would be to hack into the police department computer system and change the court date on your ticket :)

One principle for this is that whatever approach you take shouldn't cost more than 55€, either in terms of actual costs or the opportunity cost of your time.

So based on that, my first thought is that you should just try to maximize the chance that you get a court date that results in a schedule conflict for the officer.

I'd ask around with friends, especially if any is a police officer, how their scheduling works. Likely it's a weekly schedule, and if it is, I'll try to call the court to reschedule the court date to the day of the week that I got ticketed, on the assumption that the officer would be on shift. I'd do this as close to the actual court date as possible, to maximize the chance that the last-minute change either doesn't get communicated to the police department, or is communicated too late that the police department doesn't want to change the officer's schedule to accommodate the new court date.

I don't think any games relating to dressing up, or calling to impersonate a police officer or court officer would be worth the risk over a 55€ ticket, and any strategies that would take more than an hour or so of time don't seem worth it. (Honestly, even showing up to the court date doesn't seem worth the time... rather just pay the ticket haha)
