Bad drivers are a poor example. Driving is an inherently social activity. It involves subconsciously predicting other people's behaviors. Each region has its own definition of what is the norm. This includes things like acceptable speeding, lane switching behavior, average distance between cars, etc. When reality differs from expectations, we label them as a bad driver.

But are they a bad driver? Maybe. Or maybe they are driving according to another region's expectations. So any time you see a bad driver from another region, or you are the one in another region, stop and think is it really bad, or just unexpected?

For this reason I ignore all claims of "People from X are terrible drivers." No, they just drive differently.
