> There was a modeling artifact on the trail where rather than making a clear movement across the street, which is what people do in that spot, the modeling artifact suggested that you would turn left on Duck Pond Drive, then turn right on the trail.

It's been a little bit since I last biked in that exact spot, but yup this is indeed exactly what I did there as a cyclist in the real-world, and (following review of the available sources of aerial and ground-level imagery as well as Virginia and local law) is why I mapped it that way.

The alternative would appear to be riding at a greater than 45-degree angle into oncoming traffic coming around a nearly-blind corner (with under 2 seconds of reaction time at the speed limit), over a narrow bridge (signed as such), across a double yellow line, along a course with no markings, signage or legal right-of-way under Virginia law as cyclists or even as pedestrians. While I don't doubt some cyclists may choose to ride in this fashion, I'm not aware of either a legal right of way nor any physical crossing infrastructure that would support it being mapped as a lawful and on-the-ground verifiable cycleway in OSM (much less an explicitly `bicycle=designated` one, and missing crossing tags on the way).

However, if you have access to some survey data or (OSM-allowable) imagery that supports its existence, I'd be happy to take a look. Alternatively, perhaps there is there something else I'm missing here as to why this should be the preferred mapping per documented OpenStreetMap conventions?
