Since there won't be any chance that `lineIntersectsSurfaces` supports a "ROADWAY" LOD (T150513), it would be nice if we at least got some command to convert to AGLS position. (AGLS position at that position, so that `_posASL vectorDiff [0, 0, ASLtoAGLS _posASL select 2]` could return the "intersect" with that surface)
`ASLtoAGLS`
`AGLtoAGLS`
`ATLtoAGLS`
even a single such command is better than nothing (preferably ASL, as it's more common)
