That's my point, in general in OSM we prefer to set the name based on what the signage on the ground says. This whole discussion originated from the fact that the road name was changed based on another map and not from an on the ground survey of the signage, so it was unclear what the ground truth was.

You can't determine this from Google Street View, this is legally unclear and against OSM's policies, you must physically survey or use another compatible source like Mapillary, etc.
