From the screenshots and video seen thus far, the sidewalks/pavements are too wide. They currently appear to take upto 60% of a roads total width, instead of say ~30-40%.
Well, as I understand, 2-lines roads has a wide pavements, because roads can be upgrade to 4-lines, and in this case pavements becomes normal, but general width of road don’t change.
You can see it on this screen. Right road has 4 lines and normal pavements.
