There are many situations when this is for all practical purposes impossible.

For example a King vs King endgame. Even really weak players will never accidentally put their king next to the opponent.

Even worse, it's an illegal move to leave your own king in check, if I recall correctly, so that simply can't happen, not even by accident. The only possible outcome for king vs king is a draw. Unless we were to modify even more rules, of course.
