Tesla CEO Elon Musk might have his very own supersecret driver mode that enables hands-free driving in Tesla vehicles.

The hidden feature, aptly named “Elon Mode,” was discovered by a Tesla software hacker known online as @greentheonly. The anonymous hacker has dug deep into the vehicle code for years and uncovered things like how Tesla can lock you out of using your power seats or the center camera in the Model 3 before it was officially activated.

After finding and enabling Elon Mode, greentheonly ventured out to test the system and posted some rough footage of the endeavor. They did not share the literal “Elon Mode” setting on the screen but maintain that it’s real.

The hacker found that the car didn’t require any attention from them while using Tesla’s Full Self-Driving (FSD) software. FSD is Tesla’s vision-based advanced driver-assist system that’s in beta but is currently available to anyone who paid as much as $15,000 for the option. The software was the subject of an internally leaked report last month that indicated FSD has had thousands of customer complaints of sudden braking and abrupt acceleration.
