light gray sections or strips on the roads?

Sometimes in the early days of FS2020, I asked if there was any way to remove the "glued" light gray sections or strips on the roads? I hear they are related to car traffic modeling.

The gray lanes make the road look unrealistic, the closer you look, the worse it is. I don't need car traffic either, because that also eats up the smoothness of the sim, at least on my current computer.
