I can't see this working with the stock Emira mirrors. With the mirrors rotated fully outward, you still see a huge chunk of the rear of the car, particularly on the driver's side. I haven't yet sussed if there is a blind spot and if so how big it is, but it's safer to assume that there is one.I know nobody likes nhtsa, however this explains exactly what my driving coach at n M3 class shared with me. Changed my mirrors 10 years ago, and blindspot literally is Gone. Needs some getting used to, like when backing in a garage, but it works, 0 blindspots……
