I wouldn’t necessarily call it frustrating. It’s a constitutional right to face your accuser in a court of law. If a computer installed on the side of the road is your accuser then there is not a way to face them in court. You also have the right to be considered innocent until proven guilty beyond a reasonable doubt. If you state you weren’t driving at the time, and there isn’t a human who can verify beyond a reasonable doubt that he processed your license and got your signature on the ticket, you have to be presumed innocent. Both of these reasons is how and why the work zone enforcement can’t issue anything legally binding. PennDOT can codify into their rules that the owner is responsible for their vehicle then issue “violations” against your vehicle registration. An actual legally binding citation is issued to the person, who is presumed innocent until proven guilty.

As much as I wish we had better traffic enforcement, especially on highways around here, undermining constitutional rights is not a great way to do it. These are all the reasons other states have taken away most of their red light cameras and speed cameras that issue actual tickets. Most issue tickets against a vehicle and do the same thing our work zone enforcement does.
