Joking aside, its not superman vision anyways, its just a comnparative measure of the visual acuity and just how sharp you can see an object at a distance. This however does not grant you special seeing abilities. The area in the field of vision were you have this shapness of vision is extremely small, its not you full visual field as the rest is concerned with the perception of movemente and has very little contarst vision and no color. So is the object is out of were you are focused at looking, vision acuity will not help you at all.
Also you cannot scan 100% of the field of vision 100% of the time, you only see what your brain directs its attention to, and when driving there will be many things you will be scanning (cars around you, your position with respect to the road, the instrument pannel, the mirrors, the road ahead of you, etc) and many many things you will not see because you cannot focus on everything at the same time.
Even more, there will be many things that you will be were you are looking at but your brain will not "see" at a concious level because its processing other objects at that time and that object may not be deemed important enough to process compared to the others, its called inattention blindness.
So visual sharpness will help you define an object you are focusing at from a "bit" greater distance, but thats it, nothing more. It will not let you detect speedtraps that are hidden, or even those that are not hidden but you basically did not focus on.
If there is a cop behind a tree or a behind a hill top pointing a simple laser gun at you, no amount of visual acuity will save you because the cop ambushing through the scope you will see you way before you ever get to see him if you even do (give me a laser gun and I guarantee I will clock anyone here before they see me). If there is a light barrier based laser device (ex: Autovelox) set up behind a car, rock or a road sign, you will not see it cause visual acuity will not let you see through objects. If there is a simple radar (Multanova/Multaradar) installed in an unmarqued parked car pointing in the direction of traffic amongst othe parked cars or on a tripod behind a sign or a garbage container, you will not see it cause without a detector you can only see it once you passed it in the rear view after it clocked you. And so on. We even have helicopters here in Spain with a sophisticated camera-laser system (wescam mx-15) that can clock your speed from the air far away, good luck trying to see the helicopter from a far above in the sky from any direction.
It's more about luck, the type of speed enforcement in your area, if you can use counter measure devices or not and what their limitations are, etc. but especially above all IMO is paying attention to the clues (like knowing how and were they use speedtraps, which cars with radars they use (models/license-plates), knowing how the different speedtrap systems in the area work and their limitations, etc.). But good visual acuity plays an insignificant role in all of that compared to someone with average visual acuity and no visual problems who pays attention to the clues, if you have had good luck avoiding traps is more because you are good at the latter, and of course some luck too.
