Thanks, but I don't think that is the case. A speeding ticket is against the driver, not the vehicle owner. The camera ticket goes to the vehicle owner. The vehicle owner can say "no it wasn't me driving" and reveal the driver's identity - that is how corporate owners are dealt with too.
I'm not trying to stick Hertz with the bill. A parking ticket, I would pay of course. I've already paid a $30 administrative fee to Hertz for them responding to the notice from Pima County. That I am clearly bound to by my contract with them.
I may be wrong, but that is what I think the deal is from what I have read.
