Elon Musk has joked about a couple who filmed themselves having sex in a moving Tesla while in autopilot.   

Taylor Jackson, who has dubbed herself 'Tesla Taylor', filmed herself having sex with her boyfriend while the vehicle was in self-driving mode with other cars speeding past.

The 19-year-old proudly shared the clip on Pornhub where it got more than 2 million views in two days.

Now the Tesla CEO has reacted to this use of the self-driving setting by tweeting about it last night.

He wrote: 'Turns out there's more ways to use Autopilot than we imagined.' 

Musk then joked that he, 'Shoulda seen it coming…'

Jackson admitted that the pair knocked the car out of autopilot during their sexual encounter, while other vehicles drove past them.
