At least in socal with the way camera based traffic enforcement it has basically no teeth and plenty of ways like my quote to weasel out. You can actually ignore the ticket that is mailed to you. I’m not even sure HD cameras would help here. You even have options built into the ticket to say it wasn’t you driving or that it was someone else you know of in a sort of check a couple boxes and mail it back fashion. However if you actually look up the status of your ticket with the ticket number on the web portal, then it counts as being served a ticket and you do have to pay or show up in court.

Seems the way the law works is it needs some piece of two way communication. It doesn’t seem to work on a one way basis like it might in other countries. Maybe it is because most of our laws concerning technology are very much still structured for an analog world. E.g how in this case the old ritual of you being identified to have acknowledged the ticket by the cop writing it and handing it to you is preserved by you having to show you’ve actually received the ticket and consent to its validity viewing its status online.
