ELI5: Why do things happen in slow motion during something like a car crash?

Because when your body recognizes you're in an emergency, it pumps adrenaline. This adrenaline will bypass several parts of your brain required for critical thinking. You don't need to do math when there's a massive object heading your way. Because these parts are bypassed, your overall perception of time is slowed, as you have more brainpower looking at your surroundings, finding a way to either run or fight.
