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
What are you seeing that I’m not seeing to the same degree? We’re talking about subconscious biases here. I am aware the one city I visited does not represent a whole country, but being a large city, likely has significant representation in extranational communities. I do not assume a particular vehicle has a particular driver. All I assume is when someone drives unpredictably in sight (in comparison to the rest of the driving culture present), they’ll be just as unpredictable when I’m near them. Like, I’m trying to keep growing here and try to talk about why racial stereotypes often “feel” correct. I don’t see it as any different than judging your own race from a different region - for me, that’d be rude NYC people vs slow southerners or optimistic coastal Californians. I’m only talking about mannerisms that unintentionally get construed as racial.
