I’m not sure if that would be considered well travelled from a European perspective. For example if you live in the Netherlands, you could drive to Germany, Belgium, Luxembourg and France all within 3-5 hours. A quick Google says the average European visits 8 countries within their lifetime. Geographical proximity and culturally dissimilarity definitely need to be considered.
As a mixed third generation immigrant, I get this a lot. In my experience, most people want to know my ethnicity, but for some reason they never ask me that directly.
