Good news, maybe: Tesla cars are about to get new, customized horn and movement sounds, the company's CEO Elon Musk tweeted on Sunday.

Musk mentioned coconuts, fart and goat sounds for starters before adding that those are just "the tip of the iceberg."

The sound choices aren't very surprising given Tesla's infamous fart mode and Musk's sense of humor (the coconuts sound is likely a reference to a scene from the movie Monty Python and The Holy Grail(see below).

The "customized" bit in Musk's tweet possibly means that Tesla owners will be able to extend their car horn choices with whichever sounds they please.

While the horn sounds are mostly for drivers' amusement (and, potentially, annoyance of everyone else), movement sounds, which the car produces while driving, are a feature which might cut down injury rates. Fully electric cars such as Teslas don't make a lot of noise while driving, especially slowly, and per NHTSA's rules they'll need to add such a feature in the U.S. by next September.
