Elon Musk's Tesla cars are well-known for their technological advancements, from their batteries to their revolutionary "bioweapon defence mode".
But owners also get to experience a range of quirks and Easter eggs, including the cars' ability to respond to a series of voice commands.
Using their voice, Tesla drivers can change a number of settings as well as more fun options, such as switching their car into Santa mode.
Now a Twitter user has exposed a very cheeky option involving the car's charger port.
@tesla_master went public with the hack, revealing that if you say "open butthole" to the car, the charger port opens.
