In Short: players, vehicles and road sizes differ, roads compared to vehicles feel too small.
I know cars are either WIP or placeholders, but the way i see it, right now roads feel like theyre too "thin", in intersection if i have to turn, i will cross yellow/white line most of the time. Before you guys work on expanding maps, could you also see if you can change size/scale ratio of roads on old map parts to avoid this slight problem from growing into bigger?
