Let's consider a z-x-coordinate system where the minecart is the center (0/0).
The minecart moves along the line x = z, the perpendicular line to this is x = -z.
In order to decide to which side the minecart is to be pushed, it must be checked on what side of the perpendicular line the pushing entity is located. */
