From the Washington Post (which hates elon and self admittedly didn't publish all the stalkers crazy claims):
"The car’s renter, Brandon Collado, confirmed in interviews with The Post that he was the person shown in the video. He also provided The Post with videos he shot of Musk’s security guard that matched the one Musk had posted to Twitter.
In his conversations with The Post, Collado acknowledged he has an interest in Musk and the mother of two of Musk’s children, the musician known as Grimes, whose real name is Claire Elise Boucher. Boucher lives in a house near the gas station.
In his communications with The Post, Collado, who said he was a driver for Uber Eats, also made several bizarre and unsupported claims, including that he believed Boucher was sending him coded messages through her Instagram posts; that Musk was monitoring his real-time location; and that Musk could control Uber Eats to block him from receiving delivery orders. He said he was in Boucher’s neighborhood to work for Uber Eats." [1]
