Mirror usage in the US was that of the image you reference, and only recently has started to shift. Here is a comparison of the newer (in the US) and older versions: https://www.caranddriver.com/features/how-to-adjust-your-mirrors-to-avoid-blind-spots https://www.caranddriver.com/features/how-to-adjust-your-mir... The choice is not really between "blind spots" and "no blind spots" but between "one big blind spot on each side" and "two smaller blind spots on each side". YMMV, depending on whether you often drive on multi-lane roads and highways. Whether a majority of US states adopt one standard or the other is an open question. IMHO, getting USA drivers to increase their roadway situational awareness, whether by adjusting mirrors, reducing distractions, or other means feels like a cause that was lost when cars got radios and air conditioning, and drivers rolled up their windows.
