Isn’t About Memorizing a Magic Angle
This is another thing I wish people understood.
There isn’t one universal mirror angle that works perfectly for every driver and every vehicle.
People sit differently.
Vehicles are shaped differently.
Mirrors are shaped differently.
Some cars have convex passenger-side mirrors.
Some have blind-spot mirrors.
Some have electronic blind-spot monitoring.
Some have large windows.
Some have thick pillars.
So “set it exactly this many degrees” isn’t really the useful advice.
The goal is to create as much useful visibility as possible while understanding the limitations
