For example, I will save a waypoint titled "RLPGW" or "RRPGW" to specify at intersections that the road to my left or right is paved and ends in a give-way sign. Or "DWL" or "DWR" for drinking water to my left or to my right, respectively, etc. Then, when I get home, I just connect the Garmin to my laptop and comfortably upload everything using the powerful JOSM editor.
OSM's philosophy on routing is you should not try to fix routing by trying to translate your opinion that it is unsafe to ride on the street into to tags. Instead the routing algorithm should improve or the data should improve to the point where an alternative route can be suggested based on data.
Where's the feedback to the routing algorithm? I thought graphhopper / OSM was sent to users without feedback.
