I'm really surprised that the cameras actually work and they sent payment requests.... Last year, on my family summer trip, I drove 2200+ miles from Loire to LeMans to Lyon to Nice to Monaco to Like como to Milan, and being an idiot that I am I didn't know what were the "boxes" along the freeway, until when we asked the rental car company when returned the rental car in Milan before flying to Spain that those were cameras....!!!! The rental company said no worries because 90% of those cameras don't work. Luckily, a bit more than a year now, I haven't rec'd any payment requests... Knock on wood.
