I don't know if this counts, but there's picture of a truck driver which was doing the rounds:

A similar fact is that photochromic lenses will not work in cars, i.e. when you're looking at the world through the windshield. The photochemistry in them is triggered by UV rays. It's another thing that should be common knowledge, but isn't.

Unfortunately UVA contributes to skin cancer as well: https://www.skincancer.org/prevention/uva-and-uvb

Auto glass must be somehow different, because in Florida, you can surely get "some color" on your skin on a long drive and the sun beating in through the window.

Car windshields block UVA (because of their reinforcement materials to prevent dangerous shattering in an accident) but many side windows don’t.

Not sure if UVA could cause the “color” you describe. Supposedly only UVB causes tanning and sunburn. Might also just be a reaction to the heat?

Maybe it's due to heat made by Sun?

No. Definitely pink from slight burn. Google says some side windows aren't the same as the front and back.
