I have my own footage of Edewissspitze but too lazy to upload so I found the one below. It was narrow and windy. The lack of pavement or guardrails doesn't bother me, but I'd want to know there are spots to pass without having to back up.
I once stayed with friends at a mountain chalet rental in Switzerland. It had a road like that to get to it, and it was often cloaked in fog. Imagine having to back up to the wide spot in the fog.
