why is 18 most commonly seen as when you become an “adult”?

Question

Is it just because that’s when you’re done with high school? College is still fairly “expected”, so why isn’t that counted?
I don’t understand why most/a lot of cultures view 18 as that turning point, even though we know the brain isn’t even fully developed until 25.

Between the people who don’t enrol in college and the high dropout rate while going through college, a majority of people (60-70%) don’t complete any college course.
