If you thought you’ve ran out of reasons to buy a new Tesla, here’s a brand new one.

After the electric car manufacturer concealed an “Easter egg” right in front of the driver’s eyes, with its ‘Mario Kart Rainbow‘ look within the Autopilot function, Tesla strikes again with another colorful secret.

It almost seems that every new software update brings along with it a time-wasting feature that some owners can’t get enough of, and now it’s the Model S and X’s charging handle. When pressed 10 times in quick succession, while the car is juicing up on electricity, the port will glow intermittently in all colors of the rainbow creating some sort of psychedelic effect – someone was getting very bored while waiting for his or hers car to fully charge.

It’s a good opportunity to make time pass easier, although you can’t get much out of it (except a few laughs). Of course, this also could mean that Teslas come packed with little secrets waiting to be discovered by curious owners, and it’s nice that the car maker keeps everybody’s interest at peak with these sort of technological attention to details.
