Is this definitely based on GeoIP, or could it possibly be that when you look at the same city on Google Maps every day, it decides that you are likely to want to look at that city? Does the behaviour persist in a private browsing window?

I always use private browsing window (and note my recommendation on how to replicate - to use Firefox Focus as this does not have any persistent data) - so yes.

It's definitely updated on GeoIP as it's device independent (eg: a laptop using the same exit IP will automatically be redirected to that country when it changes).
