This is also a problem with Google Maps navigation. It is always showing the perspective looking straight ahead of your current direction, even when you're approaching a sharp turn. Instead, the perspective should be along a vector connecting your current location with the point where the navigation's path crosses the edge of the display, pointing straight up.
So why not use 2D maps, have people lost the ability to read North up maps? I swear ever since paper maps have not been used in cars, people have gotten spatially dumber.
That seems very wrong and unintuitive for U-turns.
