This happened to me. I am unfamiliar with the area, the rental company didn't mention it so I ended up receiving a ticket for not setting my transponder correctly. They even send my a picture on the ticket clearly showed me and my wife (2 people!) in the car. I ended up contesting it and they dropped it (first offense I guess). I bet they are relying on the fact that most people will not fight it. It's a stupid system.
