This problem was solved in 1997. Automatically zoom out and shunt the camera view ahead of the car when you're driving, distance proportional to how fast you're going. All we need to be able to see at any given moment is our stopping distance. No minimaps needed, and besides, having played with minimap mods to give me a heads up for sudden corners, I can tell you it creates as many problems as it solves when you have to take your eyes off the road in order to see where you're going.
