At the Equator, where the Sun rises and sets perpendicular to the horizon, the Summer Solstice Sun rises 23.5° north of due East, and sets 23.5° north of due West.
The Sun moves around a lot over a year. I don’t think it’s practical to try to plan a grid around it.








I believe it depends on the latitude, since away from the equator the Sun rises at an angle and not straight up. It can be low enough to still be below the visor, but risen enough to have moved far enough south (if in the northern hemisphere) to be problematic when driving southeast in the morning or southwest in the evening.
I found this image on Google search that I think illustrates the phenomenon: https://share.google/okYRf16lB1vegnVax
