I use my mirrors all the time, I just don't pay attention to them if I don't need to. Like let's say I don't need ti change lanes... I basically don't use them if I'm driving in the same lane.
My point is, I probably wouldn't notice anyone following me unless we passed like 5, 6 lights.
Too bad the US is not what the natives made it to be ๐คท... they didn't like what the immigrants did, but money is a very powerful thing.
