I am new to this game and modding in general, so apologies if this has been brought up before or if this is an extremely difficult mod to create..
Using the minimap as GPS while driving in this game is absolutely terrible. A mod that adds an arrow/line to the street telling you where to go and turn would be a huge help and probably be a top download. I found an image on reddit that shows this is available during street racing, but for some reason it is not available outside of that. Screenshot attached.
