Again - why is the driver’s ethnicity relevant?
Naturalized or born American citizens, landed immigrants, foreign workers with or without green cards, visitors on valid student or tourist visas - their ethnicity is completely irrelevant to whether they are competent drivers. If they have a valid driver’s license from any jurisdiction, and know how to drive defensively and follow the rules of the road, can drive safely; if they do not, they cannot.
And if they “resort to aggressive driving behaviors like passing in the right lane, passing on the hard shoulder, passing on the soft shoulder, “pushing” the traffic, coming up hard on other drivers (really just scaring them into thinking they are going to get hit so they get out of my way - this doent work on assholes who never watch their mirror), flashing my lights, etc.”, then they most certainly have no business behind the wheel of a car.
