Depending on how you look at it, the human eye can see 2 miles

Hey mate here is your answer》》
I can’t give you a direct answer, but a factor in its consideration would be to figure the average length of a car (if viewed from its side), then for different distances of the car from one’s eye, figure out how many degrees of arc the image of the car would occupy, then compare this to the density of cone cells in the fovea centralis of the eye, which will determine the resolution of the eye (the smallest object, or image, than can be seen as different from surrounding objects). Those at least would be the variables that a biomathematician would take into account to answer such a question. Then you also have to consider, as others have already commented, clearness of the air; terrain and obstacles; contrast with the car’s background or surroundings; color of the car (a white car could be seen at a greater distance than a dark-colored car); and perhaps other variables. It’s irrelevant to say that a human can see to the horizon, because that doesn’t take into consideration the size of the object or resolution of the eye.
If you want to do the math, you can start with the fact that the angular resolution of the human naked eye is “about 1 arcminute, approximately 0.02° or 0.0003 radians, which corresponds to 0.3 m at a 1 km distance” (Wikipedia: “Naked eye”). The average midsize sedan is 190 inches (4.8 meters) long. Happy mathing. You probably need a bit of trigonometry, which I haven’t brushed up on since high school and don’t plan on doing today.
Hope this answer will help you..《《
