In fact if you take a look at the UI in general, it's all pretty disconnected. We have 50% of the screen taken up with a visualization of the cars around you (but not all of them, and you can't 'trust' it). Next to it we have a map. The map directions are not shown on the visualization. You can't use the visualization to check for cars as you would in mirrors, as its not accurate. So why is it even shown? They could use it to show navigation routes rendered as they are seen, so offramps are shown to the user in 3d rather than the overhead map tiles. That would be actually useful.
