Skin cancer from driving on high uv days

Hello guys, asking as a fellow Australian. Just wondering if you guys use sunscreen while driving on high uv day's. Given how strong the uv is here compared to other places, I haven't really found a question about this particular problem. Most have to do with skincare aesthetics. What I am more worried about as one if the leading countries in skin cancer is if I should make it a habit to wear sunscreen while driving.

From what I understand regular windows dint really block the uv rays and I don't have the funds at the moment to get a uv tint on my windows.
