thanks!
Yes, darkness and high contrast. I love it

I believe that it does not hurt the gameplay and the road visibility at all.
There is something in the colors concept that is not yet implemented. I want add selflightened human buildings in the middle dark and cut the skyline with dark shaped light spots.
I did a quick collage:


I have a big fight in my brain with the vehicle light. By one side the effect would be cool and will overlight the vertical signs, but by the other side my asfalt singlepass pixel2.0 shader is exausted with the shadows and specularity.
In this part of the world, this kind of vehicles does not have electric intallations and lights. Is true that they do not race at night too xP
