My fiance, my brother and I are in my Tesla model y while my cousin and her friend are looking at graves when we noticed additional people started popping up on the camera and I started recording. You can hear us commenting on where they were shown on the screen, react when additional “people” pop up and tell them to get back in the car when the “door opens” and they get back in. I’ve worked for Tesla for over 5 years and can confirm this is not an Easter egg Elon added as I’ve tried this many times and it has never worked before and it’s not just picking up the grave stones as even if it was they would show as stationary on the screen.
