Yup, as a British immigrant to Spain there is precisely 1 other British person who lives here that I talk to ... most I've met have zero interest in the language, culture, or people outside of touristy things.
Meanwhile, I'm working in Vietnam at the moment, and my Spanish coworker's who came with me have the same attitude towards Vietnam.
So, I think most people just aren't interested in the realities of different lived experiences of others. Sometimes in conversation I'll dangle a lure for someone to ask me about an atypical part of my life, and 9 times out of 10 they show no curiosity.
We don't - in Spain there's an inspection every 2 years, and it's very basic (like, do the brakes work? Is the engine smoking?)
