Why would you think it's hubris? People know what they know, and extrapolate. If all you've ever known is streets with numbers for each unit being used for giving directions, you'll probably assume it's the standard. So you wouldn't even know to think "hey, do other countries use something else?". So a Costa Rican "300 meters south of where the church used to be" would be a surprise, and you'd only know it if you've been there / researched it / someone told you.

Yhere are things part of your daily life you don't even question why they're like this and if they can be another way or are indeed different in other countries.
