I am suspicious of that driver effect being caused solely by sun exposure. If that were the case we would see the same effect in all drivers.

What else do you think it could be caused by? The sun is the obvious explanation and we know the sun damages skin.
Another easy source of proof is women's skin damage patterns. Look at any old woman's naked body (if you dare) and their face, and frequently upper chest will be much more damaged than the rest of their body which has been covered by clothes their entire life.
