Yeah and till we had reliable and powerful artificial lighting, it was highly unsafe to journey in low visibility/ darkness. We used to finish journeys when darkness fell.

Animals that do require precise movement in low visibility (bats, dolphins) conditions often evolved ultrasound solutions.

So should we license Tesla vehicles to only operate when visibility and weather forecast is good and not drive in the dark at all?

Excellent points, I didn't think about the fact that even evolution couldn't come up with a vision system that works as well in the dark as it works in the daytime.

Well actually, the human vision system at night, while not as good as cats and perhaps dogs, is still much greater than any camera we've come up with thus far, I read something that claimed we can actually detect individual photons hitting our retina, once we are adapted to the darkness
