I don’t think the results of their study are completely accurate, or there’s more to the research that they haven’t divulged, such as a brain override in the case of threats. I’ve ducked or turned in well less than 15 seconds to avoid being hit by something coming at me. If all I’m seeing is what I took in 15 seconds ago, I’d have been dead a long time ago.

It may be more accurate for the researchers to conclude that the brain holds on to multiple images for 15 seconds to enable complete processing of the landscape or field of view.

Makes more sense, that way.
I used to quiz my kids in driver training to recall the last vehicle they passed; which side? car or truck? What color?
Then check the mirrors to see if it is still there behind them.

This is a technique the military teaches known as “compartmentalization”.

Wouldn't be too good for boxers or tennis players or race car drivers or pretty much anything else.
