Swiss-French border error in Country Streak
(url/game ID for reference: https://www.geoguessr.com/game/ZDwK75vbWEUR6A5q)
It looks like there is a French road (marked with a French yellow "D15" sign at the T-intersection in Streetview) that runs directly adjacent to the border with Switzerland. The game spawn marker is clearly on the French side by ~5 meters, but the game marked my guess of France as incorrect.
Honestly, I'm not even mad, I'm still laughing about it. It was a good streak though...
