Run a search for "auvent motorisé" for region France. And notice half the results are not from France. And even very obvious ones, like domains ending in .be or .ca.
This is clearly not filtering by region France at all, french at best.
Rant: I literally subscribed to Kagi a few minutes ago because Google and DuckDuckGo have the same issue and I thought Kagi was going to be better. Turns out the results are 99% identical to both Google and DuckDuckGo so far.
