On the plus side, he could also contest legitimate tickets unless they recorded other information.
Each day there was a 10-20% chance I would get a ticket on my windshield. I would collect them and take them to the uni security office once a fortnite to have them cancelled in bulk. I actually got pretty friendly with some of the staff there.
At least 4 of them were legitimate tickets because I parked overtime, over a line, etc, but the staff cancelled them anyway (:
