Also, mirrors that curve near the far end. Each time I visit US I'm frustrated by the american cars having flat mirrors. The blind spots are insane. I guess it's due to some weird regulation? In EU mirrors have their last 2-4cm curved, and there's virtually no blind spot, and you don't need to adjust mirrors too precisely even.
