At the moment, our present format does not support elevation data but, maybe later in papago format.

In practice elevated roads are not high enough above the terrain to reliably tell the difference
When you are on the road underneath, the signal is degraded with a lot of reflections, reducing accuracy quite a bit.
You are right.
