TIL:
Rearview “mirrors” that are actually screens are popular in fancy cars these days ... requires the driver to focus on the surface of the screen itself, which is mere feet away from their eyes. This is a large change in focal distance from looking at the road ahead.
Actual mirrors allow the driver’s eyes to focus on the road behind the vehicle, rather than the surface of the mirror. This is a much smaller change in focal distance, and is therefore easier, faster, and more comfortable.
