Traffic violations are so common that I think perfect enforcement would almost instantaneously lead to changes in the law.
The first day of perfect enforcement in Northern Virginia, for example, would lead to about two million tickets being issued. After the entire legislature had been strung up by their thumbs, the new legislature would no doubt realign all speed limits and other laws to match how people actually drive, rather than some insane ideal of how they should.
I have friends working in traffic departments for various cities. They tell stories of sending out speed recommendations based on the design of the road, houses, intersections, etc. The speed limits come back from the politicians much reduced.
Roads are designed to be driven at a particular speed. This is the speed most drivers use.
Having a lower speed limit gives a false sense of safety. It's basically the "think of the children!" argument.
The politicians would simply carve out exemptions for themselves. I have seen no evidence that .gov has ever been this responsive to the impact of the laws they write.
