It doesn't seem like there are any other cars on the market right now that have as many easter eggs as Tesla's cars do.
Most of them are even hidden directly in front of the driver, but chances are you haven't even seen them.
If you press button on your Tesla's charge handle, the light around the charge port flashes rainbow colors.
Something to keep you entertained while you wait for your car to charge.
If you've purchased Tesla's Autopilot software, turn it on four times quickly to display a Mario Kart-like rainbow road on your gauge cluster screen.
Elon Musk referred to this rainbow Easter egg as a "psychedelic cowbell road."
