It drives me nuts when Google Maps presumes I can think in different units whenever I travel.

Yes, I'm in Italy now. No, that doesn't mean I forgot how long a mile is, or have instantly learned to judge the world in meters.

In some Muslim country Google forces you to use the Hijri lunar calendar. There is no option to switch to Gregorian. Google knows best and everyone in that country wants Hijri.

I could understand making that an option though, as presumably the distances on signs will be in km. But as usual with this sort of thing, it's developers assuming they know best rather than suggesting and asking.
