That moment while driving when the pavement is wet and the sun is at a low angle and suddenly the ground is as bright as the sun and you can’t see anything. But all the time!

It sounds more complicated than just figuring out how to prevent glare. Even if you do that, the terrain will always be illuminated in this strange high contrast scenario. I find myself thinking about how photographers use reflectors to avoid this in their portrait subjects.

Meanwhile, solar panels might be super efficient because they get to use the moon as a giant reflector. Shedding heat will be an interesting problem though... perhaps thermal panels and Stirling generators instead of PV? They could save a bunch of weight by just using the water-ice when they get there. Sounds like a fun project to work on!

Did they consider a helmet filter that put a dark spot over the sun dynamically? Perhaps with an lcd layer.

I forget which one, but there's a Larry Niven science fiction story that uses this as a plot point. Our hero takes advantage of the sun blocker spot on the villian's plane or ship by approaching in the line of sight of the planet's sun.

Grendel, one of the stories in Neutron Star, set on a planet orbiting a very bright star where everyone has to wear protective goggles with sun-tracking black dots for each eye.

Our hero needs to steal the bad guy's (flying) car, at sunset and circles until his shadow points at the car..

This is a very old fighter pilot tactic.

I believe this strategy was also used in WWI, but just hiding in the glare of the sun.

For 20 years, I’ve wondered why we don’t have that in cars.

Its a tough feature to implement- the sun's position in the glass depends on your perspective as well, not just the sun's position in the sky.

Easier to do in a helmet than in a windshield, I suppose.

Imagine blocking the infestation of billboards on earth with a dynamic shade.

In some place the entire windscreen would be blacked out

Sounds expensive. I propose a dynamic directional umbrella hat.
