There was such an objection that they developed the tunnel box instead. At this point, I'm guessing all we're going to get from staff is something to the effect of "you told us that assuming that a negative elevation was a tunnel was a bad idea because negative elevations were being used for other things as well. Well, what were you using them for other than tunnels?" Eventually, it seems likely that positive elevations will be shown as bridges and segments with the tunnel attribute will be treated as tunnels. Other than that I'm not seeing that elevation matters at this point.
Don't forget that MapSir already mentioned this in locked V1.11 beta thread when tunnels was about to be released. We already have our answer from Waze on elevation. -1 IS NOT a tunnel. The tunnel option is what makes a road have a tunnel. Not -1. SO, mapping underpasses as -1 is normal.
