In no definition is "near miss" a hit, even taking it "literally" near is adjective for the noun miss, so it is a miss that is near. i.e, a miss where two bodies are close but don't hit.
"could care less" only exists out of misappropriation of the original idiom though, which is "couldn't care less" - a phrase which makes far more sense.
But it's used in the sense "too close and not within acceptable margins". It's not a collision, but one might just as well think of it as a "hit" - someone messed up.
"near miss" just means "that was close", or "we almost didn't miss" -- in other words, "we missed, but we were pretty damn close and could have collided".
It doesn't mean "nearly missed, but actually hit" -- check any dictionary.
