The thing I don't get is that there are plenty of Googlers traveling internationally. They've been aware of the problem for over a decade now, yet it persists. If I'm traveling from Spain to Poland with a browser set to use UK-English, why would the site immediately switch to Polish? It makes no sense that this common corner case isn't addressed at all after all this time.
At the very least sites that do this should detect that there's a mismatch between expected language given geolocation and the header and have a toast notification about how to change the language settings back manually.
