Elon Musk teased an upcoming Tesla feature that combines external speakers and artificial intelligence, enabling vehicles to “speak” to pedestrians. The billionaire said that other than conversing with humans, drivers could emit a fart noise from the speakers as well.

He shared a clip of the technology on his personal Twitter page, which highlights a Model 3 driving through the streets and speakers playing “Well don’t just stand there staring. Hop in.”

“Teslas will soon talk to people if you want,” he said in the tweet. “This is real.”

The speakers have been added to the electric vehicles under the Pedestrian Enhancement Safety Act of 2010. This law requires electric vehicles to emit a noise when traveling at speeds lower than 30 kilometers per hour to compensate for the relative silence of their engines. And Tesla placed theirs in the front grills of each vehicle.

It is not clear why the firm would include a fart noise as an option, but Musk has previously teased this feature before. In October, he noted that owners could soon customize the sound of their car horns and one of the noises includes a fart sound. The CEO stated the horns will include a range of sounds including goat bleats and the sound of clacking coconut shells. He also noted that he would be open to letting customers upload their own sound files.(SD-Agencies)
