I have just added this comment to the page https://wiki.openstreetmap.org/w/index.php?title=Talk:Proposed_features/hazard Subdivision of the hazard namespace
To me it would come naturally to subdivide the namespace as follows for different users of the road: - hazard:general= - hazard:pedestrian= - hazard:motor_vehicle= - hazard:bicycle= - etc. (This could absorb 1:1 the existing cycle_hazard tagging) The main reason for such a subdivision is obviously that the hazards for the different users are different."
