I've used the Apple Maps navigation during the last vacation in Spain (rental car did only support Apple car play), and the navigation desperately needs some love. The worst things are:

- no support for roundabouts: it's really hard to determine where you have to leave, and the spoken hints are not helping. Why not displaying a top view of the intersection/roundabout like other navigation devices do?

- no good support for leaving a highway. If the connection is non-standard the speech commands seem off/hard to understand. Top view again would help.
