Teslas now have built-in "whoopie cushions" thanks to a new firmware update. The vehicles can now make farting noises on demand or by use of a turn signal with what they're cheekily calling, "Emissions Testing Mode." Jalopnik reports there are seven flatulence sounds to choose from -- "Not a Fart, Short Shorts Rapper, Falcon Heavy, Ludicrous Fart, Neurastink, Boring Fart, and what seems to be a fart randomizer."
There are two other bizarre Easter eggs in this update: Romance Mode and Pole Position. The former provides a virtual fireplace and the latter is a retro-modern version of the old school racing video game.
