The "Carolina Squat" modification on a Cybertruck involves raising the front end of the vehicle while simultaneously lowering the back, causing the truck to appear as if it is squatting. This modification can affect the vehicle's performance, handling, and safety, and is currently illegal in several US states.
The YouTube video of the modified Cybertruck is accompanied by Kendrick Lamar's "Not Like Us."
Joe Fay initially responded to inquiries about the modification by saying there was a "secret menu." Later, he posted a full tutorial on TikTok for his fellow Cybertruck owners.
