OSM is intended to reflect the ground truth. In this case, it is a permitted turn, with no "Dangerous Intersection" signage, so the map must reflect that.

While navigation advice is out-of-scope for OSM, the very natural desire to avoid a particular bit of roadway, by an individual driver, can be done individually, off of OSM. For example, I use OsmAnd, and have added many "Avoid Road" markers for my own navigation. Telling your nav app to avoid the road segment just after the turn would serve that purpose here.
