The electrek.co article I linked to says, quote:It looks like his wife was driving it.
"A Model X owner claims that his week old SUV accelerated on its own in a parking lot and autonomously crashed into a building at high-speed in Irvine, California.
Tesla Model X owner, Puzant Ozbag, posted his story on the Tesla forum this weekend."

So it sounds like he was driving. That said, I would not rule out that his wife was driving the car. He states: "The airbags deployed and my wife's arms have burn marks as a consequence." If his wife was in the driver's seat with her arms on the wheel and the airbags deployed when the car impacted the side of the building, the steering wheel airbag could have rubbed across her forearms as the bag inflated.
It really doesn't matter whether Mr. Ozbag or Ms. Ozbag was behind the wheel. At this point we don't know for sure.
Let's see what Tesla has to say about the vehicle logs. We will hear in due time...
