Memorizing the location of fire exits is also obvious and yet we do drills to burn it in because when you’re in the shit it’s hard to think rationally about this kind of stuff.

I don't think that's what the drills are for. You do drills so that everyone is familiar with an organized process of exiting the structure, so that an evacuation can occur quickly.
In the absence of drills, everyone will still know where the exits are, but they'll form giant traffic jams that block people from using the exits.
A little repetition is good for the monkey brain.
