I see that I have probably chosen an unfavorable solution to solve the
problem described. Many seem to accept the basic problem: There is only
one qualitative category for all kerbs with a height of over ~3 cm,
although in reality there is a significant difference.

I see two alternatives to the proposed solution:

a) (as suggested in the vote section) Deprecate the category "raised"
and introduce two /new/ values ​​to differentiate it (eg "heightened"
vs. "regular" or "medium" if there is sematic criticism of "regular")
b) Keep the existing categories, accept that the term "raised" has so
far included both normal and raised kerbs and merely introduce an
explicit tag to distinguish /actually/ raised kerbs (e.g. "heightened").

What do you think? Any other or further suggestions?

P.S. The advice to specify the height precisely in cm instead does not
lead any further - as discussed in several places -, since precise
height information cannot be collected on a large scale and remains
optional. It is not without reason that there are qualitative curb
categories - just one too few. A typical intersection has about 8 curbs,
which I can assess qualitatively with my eyes within some seconds while
passing, but I need a few minutes to measure them all with a ruler...
