I took a similar class almost 20 years ago, and it unquestionably kept me from at least 2 serious accidents, and potentially saved my life. I cannot recommend them enough to new drivers, it’s absolutely the most dangerous part of our daily lives.

And yeah, these mirror settings are the absolute best way to drive. It takes some getting used to, but there are absolutely no downsides to having a wider field of vision.

When adjusted like this, you can still easily see the side of your own car by moving your head slightly, which is trivial when backing up.

I learned about this in a driving class almost 20 years ago and never looked back (pun fully intended).
