I'll add points to suggestion:
3) GPS fix at end of tunnel is not accurate. It often puts my car to some other road around and needlessly recalculates route. It is few seconds, but if there is crossing at end of tunnel, it is problem.
4) Exits which are underground. At current state app gives no instructions (only those before tunnel). If speed is simulated it can give good approximation where exit is.
Inspire in other navigation software (I used Sygic before Waze). They do simulate by road limits, but Waze is much better as it knows actual speed of other wazers.
