How to complete Unauthorized Passenger in Potato Please

Potato Please has a hidden “Unauthorized Passenger” achievement that rewards players with a completionist tag. It is not required to finish the game, but the challenge is easy to miss because the game does not explain how to complete it.

Players must first unlock the costly Sack Cableway upgrade, which has several prerequisites and is best left until later in the game. Place a sack of potatoes beside the cableway and wait for it to pick it up, then press E while holding the sack to be carried through the air; jumping on the sack will not work.
