When Bart turns off auto-pilot in the Electric Car, the steering wheel folds out in the same way as in the 1993 film Demolition Man.
In Elon's spacecraft at the end, it is shown on a monitor that he is playing The Simpsons: Tapped Out.
The Song playing during the credits is "Starman" by David Bowie.
This episode has no Opening Sequence. Like Sideshow Bob Roberts, it just go to the TV set showing "Created by: Matt Groening." "Developed by James L. Brooks, Matt Groening, Sam Simon." Making this the third time since The Great Simpsina (but without The Simpsons logo and begins with the Simpsons go peach picking) to have that occur.
This is the 13th episode to not include a couch gag.
