It seems Google has never been able to figure out that people actually travel between countries, which is amazing given how much the Googlers I know move around.

Great example is translations... often various Google properties speak the whatever local language to me, even though I'm logged in. While it has been a while since I've seen GMail in Turkish, this still happens frequently with search.

Two issues here:

1. my Google account knows what language I want to use

2. language !== country. Many countries have multiple official languages, not to mention immigrants etc.
