It is just a joke, alright. I get that. It might have been funny in some way, but it does not work for me in the current version.
It may be a coding exercise, but there is not much exercised here: "straight" and "left" and "right" are not defined as proper directions (the game simply demands the cardinal directions to be used -- in a way that makes them meaningless), the commands not in use are not implemented or deactivated (so "X car" produces the standard response of not seeing any such a thing), and there is no proper ending (the player ends in a room called "End Game" with the room description of the victory). There is no prose -- some descriptions should have been added to convey a feeling. These are just some of the things which might have been improved and which deviate from what I am used to find in Z-code games. Joke games are okay, in fact I like them. A short play with a punchline, a nice ending -- it is good. But jokes can be polished too. The basic idea is not bad, but needs more prose and some improvements.
