Or you could do what most I do when I'm in Italia: zip through the Telepass lane and consequences be damned.
Top tip: they'll eventually tie it back to the rental car you were in and then the car company will try to charge you. Just remember to cancel the credit card you used for the rental and get another one with a different number and voila: free autostrada tolls. Comes in handy for speeding tickets too. Rental car companies will try to charge the card they have on file but it's no longer valid.
So sorry non posso pagare...cazzi vostri!
