Once a Ca LE entity confers LE powers on an individual that person can observe and cite without a stop as long as there is positive ID. That's precisely what the challenges to red light cameras revealed. No ID? No plead guilty, yes walk away.
The whole point as articulated by Berkeley people, is to virtually eliminate "routine" traffic stops. This is safer for cops and motorists. Let's be real for a second,
in cities there's almost no traffic enforcement for infractions. CHP is the exception, but they target problem areas as a rule.
What I mean by "tech, not stops" is a traffic enforcement car will have cameras and if facial recognition gets a hit, and the violation is observed by someone with LE powers, boom, you get a ticket and that person's sole job will be to show up if it gets contested. All you have to do is beep your horn and people will look over right into the HD camera. Not to mention the network of thousands of cameras all over cities everywhere.
Where camera footage ends up and how it's secured is their main limitation. Cloud services ain't cheap and cities are broke as hell. All laws are "mere suggestions" and the old saying "when seconds count the cops are minutes away" is true, except in cities where hours are more the norm, unless you're in a rich, low crime area. It isn't low crime because rich people are more law abiding, they just aren't slugging it out for survival and tripping over laws designed to discriminate. No, the penal code is not objective. :x
We need more funding and better training for cops, not less. Our city loses half it's new officers to the sheriff after a few years cutting their teeth. Better pay, better conditions there. What do they cite as the reason for leaving? Poor working conditions due to understaffing. The "be careful what you ask for" argument doesn't carry much weight when you look at data:

"Events like these provide rare opportunities to explore questions that couldn’t be tested experimentally, for practical or ethical reasons. So Sullivan and O’Keeffe looked at crime statistics for the duration of the slowdown, and they found something surprising: reports of major crime dropped during the slowdown period."
