It sounds like one of the items you’re getting at may be separating nationality/ethnicity stereotypes from race stereotypes. Immigrants or children born in another country will have varying degrees of that cultural as part of their personality. Bartering comes to mind with Indians.

One I experienced recently was Hispanic drivers. We have a fairly large Mexican population here but I obviously can’t tell by appearance. There’s a certain combo of vehicle, modifications, and asshole driving style that would indicate to me the driver was probably hispanic. I took a trip a manufacturing Mexican city (read:non-Resort) and was shocked by the drivers. I saw the wildest maneuvers to get 2 cars ahead, every peice of pavement was valid for driving, and speeding is only avoided at checkpoints. Yet, I didn’t see any accidents, I didn’t hear any horns, I didn’t see any road rage. It was aggressive driving, but everyone just existed and cooperated. Obviously, if you’re the only one doing it, it makes you unpredictable and therefore it’s reckless, but damn, that adjusted my opinion so fast
