True, but convex mirrors help a lot. I'm not sure do all cars have them, though...

  Federal law prohibits them on the driver's side in the US[0]. [0] https://wheels.blogs.nytimes.com/2010/12/30/in-defense-of-convex-drivers-side-mirrors/ https://wheels.blogs.nytimes.com/2010/12/30/in-defense-of-co...

    Clarification: federal law permits them on the drivers side in the US as long as the mirrors also have the required flat mirror [0]. [0] same link, and the fact that my vehicle came from the US manufacturer with both.

      I have a 2017 Ford Fusion with a "blind spot mirror" (i.e. a small convex mirror in the corner of the flat mirror) and I have no idea why all cars don't have them. With the left and right mirrors adjusted to just barely see the edge of the car, I have no blind spots (assuming you are careful to check the small mirror separately from the main mirror.)
