>From the osm perspective, all these extra bits of information may not
maped yet (road width, vegetation height...) or ever (relief). Even
when they are, deducing the visibility algorythmically is hard. You
might not want to render hazard=curve, but still want to provide it to
drive-assist software.

As for drivers being aware of their suroundings, if the local
authority decided to signpost a curvy road, it's a good hint that osm
should as well. It's not much different from tagging maxspeed.
