Using smoothness=* for HDM purposes. Replacing surface_condition=*.

Discussion

Simplified to very simple definitions of values.

Only using smoothness=intermediate to represent it is practical to drave at speed of over 40 km/h.

And smoothness=bad for roads that are not practical to travel at over 40 km/h. Will add this supplementary def to wiki.

You really shouldn't do that nor propose to do that ! Because you are proposing to use an allready existing tag for a different meaning that it was proposed for, which mean the tag will be ambiguous. smoothness=bad means you can drive on it with a "normal" car, not that you can't drive over some arbitrary speed. If you want to add this information, you'd better use another tag like can_drive_faster_than_40=yes sletuffe (talk) 21:31, 17 May 2013 (UTC)

You should probably take a look at this and also at this discussion, and hopefully get involved.--Fernando Trebien (talk) 16:23, 21 March 2014 (UTC)

Another tag

You could use surface:grade=* for that. Its value "depends" on surface=* value, that is, it isn't absolute like smoothness=*. So "Rough" could mean surface:grade=1, etc. The downside is that tag is not "official", though it has been used 1250 times as of now. --Zverik (talk) 13:18, 21 June 2013 (UTC)
