Two paths are created for going over a mountian.

One path (path D for direct route) is a straight line to the top
and a straight line to the bottom on the other side.
Another path (path C for curved) is a curved path to the top
and a curved path to the bottom on the other side.
The distance bewteen the start of the paths to the end of
them is the same and we can use a tunnel to prove such
of course.
So...
What path would need more final energy use to follow?

Your curved path just happens to coincide with my
orbit. I am not wasting fuel to decelerate and
negotiate your tunnel.
