Tesla Model S

While the other cars on this list on this list have design-related Easter eggs, Tesla has gone for features hidden in the car’s software. Tesla boss Elon Musk is a massive nerd, so he has packed his cars utterly full of pop culture Easter eggs, including the famous one that replaces the Model S on the settings display with James Bond’s submersible Lotus Espirit (which Musk actually owns) and the Ludicrous setting that alludes to the Mel Brooks film Spaceballs. Other hidden treats include one that turns the sat-nav into a map of Mars, complete with Mars Rover, a Mario Kart reference and the latest one that turns the massive centre touch-screen into a sketch pad.
