How about making a lot of loud and "pleasant" noise so pedestrians know there's a noiseless Tesla electric vehicle (EV) in their immediate vicinity? Sounds like a good idea and you know it is when Tesla CEO Elon Musk gives it his nod.

Tesla EV noisemakers include "pink noise" for its EV's forward sound and a sci-fi-esque tone for reverse driving. Now, Musk said Tesla will expand its safety noise collection to give Tesla owners the ability to choose the sound for their EV's noisemakers and horns.

Musk has revealed Tesla EVs will "soon" have the option to customize horn and low-speed movement sounds. He also confirmed outlandish sounds are coming in a tweet Sunday:

"Customized horn & movement sounds (coconuts being one, of course) coming to Teslas soon."

Musk said he "will consider" allowing custom upload sounds, but this might prove more of a problem than it’s worth. Imagine "crazy" drivers creating their own "crazy" (think obscene) horn and movement sounds that might be too distracting from a safety standpoint.

For now, Musk said what Tesla owners will get (among many others) will be a collection of noisemakers meant to improve pedestrian safety.

These tones include a whoopie cushion fart noise (made infamous by Tesla’s “Toilet Humor” mode), goat bleats, rushing wind and the coconut horse clops from the 1975 hit British movie, "Monty Python and the Holy Grail," Brits still consider one of their top five comedies of all time.

Musk has approved a request by the Tesla Owners Silicon Valley for Jungle and Rainforest noises. He also said Tesla will explore custom audio files, so owners can include any noise they want. Tesla also said there will be additional noises yet to be determined.

Tesla has also installed Easter Eggs in the software. One Model 3 owner discovered naming his car after Holy Grail's killer "Rabbit of Caerbannog" created a Tesla Theater shortcut to Monty Python videos on YouTube.

Apart from imparting fun, the new sounds have a more practical safety aspect. They're expected to save some 2,400 people from injuries. They'll also save somewhere from $250 million and $320 million in damage from road accidents.

Tesla’s decision to add the noisemaker complies with the National Highway Transportation Safety Administration‘s (NHTSA) Pedestrian Enhancement Safety Act of 2010. The NHTSA passed the act upon finding that blind pedestrians were subjected to additional risks when in the same vicinity as EVs due to the EV’s lack of noise.
