I am not a lawyer of any kind and this is not legal advice. I'm merely speculating based on my past experience with other tickets on how I might handle the hypothetical scenario being discussed. It's up to the state to prove their case. I'd contest any such ticket with the truth. Likely these systems are profitable because people don't generally contest the ticket (or do so in ineffectual ways). Neither the private company nor the state wants any judge making a ruling that makes such tickets impossible to enforce. I'd expect it would get dropped before I'd ever have to talk to a judge, but even if not, unless they have clear evidence I am lying, they're probably going to lose in court.
