I doubt it. All the toll lanes that accept EZ Pass that I've seen are equipped with cameras. These cameras are used to identify toll evaders already. You point out that doing this would require manual work, but in fact several systems (including the one used for handling traffic fees in central London) have already demonstrated that automated license plate reading systems are feasible. Even without automated plate reading, storing photographs is also now astoundingly cheap given how cheap storage has gotten, so if anyone ever complained about incorrect charges on their bill, finding the plates of the cars that went through during the disputed toll collections would be trivial. Unlike cellphones, this is not an instance where it would be easy to get away with theft by cloning.
