I don’t agree. Your examples are both extremely touristy and stereotyped heavily in media... largely produced in those locations. The regional stereotypes I’m familiar with are... stereotypes. They’re true. They just might not be true about any particular individual who lives there. And they’re true because these are largely learned behaviors. Are they useful? Well, in aggregate they might give you some patience and understanding if you’re going to that region and have to interact with the people. Lots of behaviors you might consider rude might actually be friendly or at least polite there. And while you may not be able to assume an individual from a place matches the stereotype, it’s a pretty safe bet if they match the stereotype they’ve got a connection to the place.
