"So waze's only option would be to clamp the car to the street it is driving on and predict the position with the latest speed."
I totally agree. The algorithm I would use is if road elevation < ground level && gps lost then propagate the estimated position along the Waze route at the last known speed. When road elevation returns to ground level or above then freeze the position until gps returns.
Seems such a simple implementation to me for what would be a huge benefit. If there is an exit half along the tunnel you get no guidance. What use is that?
