"INSANE SUN GLARE WHEN DRIVING IN 1ST PERSON"
Although I agree that it's way too bright sometimes, I do think that it's a normally functioning game mechanic meant to serve as a challenge during driving. The solution for it is simply switching to 3rd person view. As I like to accept the challenge, I slowdown to a speed with which I can see. It's just one of the many game mechanics meant to add more realism, challenge and flare to the game, if you ask me.
