This can now be automated. Video the activity, provide the necessary markers (maybe a time based hash or whatever) so the provenance of the video is sound, and follow the general rules for evidence gathering and chain of custody, archive it, and send the car owner a bill. Increasingly municipalities are making these kinds of things civil offenses, not criminal, so they can attach liability to the car owner for some kinds of infractions. Whether that stands up to the state's highest court without a state law, IANAL so I dunno. Next, eventually there will be just enough autonomous cars, all of which will obviously only ever go the speed limit, and at least in moderate traffic it'll effectively prevent human driven cars from doing the usual bad shit; we'll be left with the edge cases of just really bad shit.
