and UV imaging of drivers faces commonly reveals large difference in UV skin damage on the driver side Is this true for the general population, or just professional drivers who drive 8+ hours a day? Auto glass blocks a significant amount of UV radiation, and one certainly doesn't see people walking around with lopsided facial tans. It seems to me that for a significant amount of UV light to reach the side of a driver's face: - the sun would have to be rather low in the sky (at which point a significant portion of UV radiation is blocked by atmospheric scattering anyway) - the window would have to be rolled down - the car would need to be traveling in a specific heading (if the sun is low in the western sky, the driver would need to be traveling north in order to have significant exposure)
