The fastest course is not the fastest

On a curved road, the in-course (A) can move ahead faster than the out-course (B).
So we tend to think of this as "the fastest course." But this only means that A is better than B under the constraints of "course." If we remove the constraints, straight forward C is the fastest and by far the fastest Compared to C, the difference between A and B is nothing.

Are these "constraints" really unmovable, or are they illusions created by the human mind?
A runs on the inside of the course, a little ahead of B, and feels superior.
But hard to see, the off-course C is far ahead.
A thought he was the best, but suddenly C appears so far ahead that he can't catch up.
From C's point of view, A and B are not much different.
