Re: Road textures from cockpit view way too bright
Temp workaround (*but definitely not a good one) is to reduce the sun's intensity in the bottom of your Engine.ini under [SystemSettings]
[SystemSettings]
r.SkylightIntensityMultiplier=0.5
You can do any amount you prefer.
*I say it's not good because it only works on PC, and it darkens the lighting from the sun in every stage and every time of day. So objects on the side of the road, and sections of the road shadowed by trees or whatever will also be much darker. You'll have to remove or adjust this for each individual location and lighting condition. And it does not resolve the core issue of the unnecessary autoexposure/eye adaptation being enabled while inside the cockpit. That's still happening, so exterior views will also be even darker.
Anyway, this is what it does to daytime in Mexico.
default: 
r.SkylightIntensityMultiplier=0.4:

It makes things even more unnatural the other way with the harsher shadowing and dimming, but for some it may work a bit better for road visibility in certain stages and conditions than just reducing the game's brightness on the whole (these were SDR w/ brightness at the default 50) until they figure out a way to ditch the exposure junk.
