We have known for some time now that Americans get more skin cancers on the left side of sun-exposed areas like the forearm, face and neck since we drive on the side of the car (and we do drive a lot).
More recently, it seems that the amount of ultraviolet (UV) sunlight that can get through the closed side window of cars can be quite high.
The windshield typically blocks 96% of UV. This is due to its 2-layer construction that makes it hard to shatter in a crash. On the other hand, side windows are not required to be so crash-safe. Some models (such as Lexus) block as much as the windshield. Others only block about 70%.
Until side windows catch up, the best way to prevent skin cancers due to this exposure is to apply some sunscreen before you drive.
It's also worth remembering that applying some SPF 30 every day (even if you are not going out) prevents skin cancer, both prevents and reduces freckling and moles, and also prevents sun-related wrinkling and aging of the skin!
