“Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience.” ― C.

The problem is as we get perfect enforcement, the delta does become visible. The reality is that when a road is set to 55 mph, that is not some sort of pronouncement from God that that is the one true speed that the road is safe at. It was just an approximation. But then we set up a camera that treats it as rigid ground truth, and now you can be nailed with a ticket if you're doing 56 miles per hour.
But does that help anyone? Was anyone unsafe because you were going 56 mph rather than 55? No, of course not. 55 was never the point. Nominally, safety was the point. Safety is not about going a single speed. There are days and conditions when 65 is practically as safe as 55. There are days and conditions where 65 may be safer than 55 (e.g., everyone around you is doing it on a multi-lane road, you're safer following along than stubbornly insisting on being 10 mph divergent). There are days and conditions where the safe limit may well be 15, or even 0. That's the real thing we want. But that's not what computers and AI give us. They give us rigid enforcement.
As society develops the capability to enforce laws rigidly, it will need to figure out that rigid enforcement isn't what we ever wanted. The laws were not themselves the end goal.
Unfortunately, this is going to be harder than it should be because this rigid enforcement creates and/or reinforces a power center in the people who will benefit from this rigid enforcement, both monetarily and through the additional power to selectively pardon people for what is de facto a brand new set of crimes, in the sense that the are a whole bunch of convictions that could never have occurred in the past. Modestly clever use of the pardoning process will allow them to hold on to that power for extended periods of time by using it to cover over the worst and most socially costly offenses (see also "Support via working out how to raise enough of a Twitter fuss to get the company's attention"; you can suppress outrage and even look magnanimous by pardoning the things that get into the news while hammering everyone else).
We will, of course, have to learn this the hard way.
