Thanks for the update.
Is being able to see while driving in First Person during the day still a big ask?
If you are on PC, using my mod called
Eye Adaptation Complete Overhaul
available on Nexus Mods is a valid option. Of course, it's not yet updated for 1.61, but it works perfectly fine with 1.6 and will soon be updated to match the new version of the game. You have to combine my mod with Better Vehicle First Person which is linked and explained in the pinned comment in the POSTS tab of my mod on Nexus Mods.
In terms of modifying the camera/exposure system and how it relates to rendering techniques, absolutely. A working fix that makes driving in FPP possible, no.
Change the windshield shader opacity to match the driver and passenger windows. Yeah, from the outside it won't look "right" having a tinted windscreen but it will serve the purposes of driving in First Person... in a First Person game. Anyone would be too busy driving to really care and the opacity level can be scripted to vanish for photomode if people bitched about it.
That's not how any of this works. Tinting the windshield won't do much because in majority of exterior areas in the game, the auto exposure IGNORES what's in the center of the screen (i.e. the windshield and what's outside of the vehicle). Instead, it prioritizes the pixels somewhere inbetween the center and the edges of the screen. This overexposes the image when driving in FPP because the interior of the car is prioritized and the interiors in most cars are obviously going to be black or dark grey, especially when you're driving under bridges, in tunnels etc. and this contributes to the overexposure with the vanilla auto exposure configs. The game tries to brighten up the interiors, blinding the driver in the process by overexposing the windshield.
The auto exposure issue in first person vehicle driving stems from how the auto exposure is configured in various parts of the game's world. What could work is if they made a vehicle-based auto exposure config, but mind you - there are some locations in the game where auto exposure goes crazy even outside of vehicles.
Since there's no vehicle-based auto exposure config, my mod instead edits (to a various degree) all auto exposure configs in the game. You really should try it so you understand the difference. My solution is not perfect because it affects the presentation of the game a little bit depending on the location you go to (some remain unedited in my mod to preserve vanilla visuals), but it's the best one I came up with.
As for console players, I can't help there.
