Great news! The Waze Beacons Program is in the works and constantly expanding.
The Waze Beacons Program is the first scalable, affordable solution in the world to power navigation in tunnels. Currently available in select tunnels throughout Pittsburgh, Haifa, Israel, Paris and Rio de Janeiro – seamless navigation is available to Wazers underground simply by turning on Bluetooth functionality.

Yes why can't they just have the position move through the tunnel at the same speed as was detected before the car entered the "tunnel" segment. Will be close enough and will result in getting the correct exit instructions. If you get held up in the tunnel then the position would stop when the position reaches a non-tunnel segment and GPS is not available. Seems easy to implement to me, no beacons, no attempting to simulate an inertial navigation system....
