A San Francisco passenger claimed a Waymo driverless taxi drove down with his expensive tennis equipment. More than two months later, he still didn't know where his property went.

As San Francisco Standard first reported, the passenger is filing a small claim lawsuit against the company.

Dan Linley lives in Nob Hill and walks back and forth between his job as a high school tennis coach and coaching tennis classes.

"I've been 30 years, and that's how I make a living," Linley said.

Like many San Francisco people, he doesn't have a car. Recently, he has been taking a Waymo driverless taxi to the city.

On February 7, around 5:30 pm, Linley said the Waymo he was riding sent him to Golden Gate Park, but the trunk was filled with his expensive tennis equipment but it didn't turn on.

Waymo said on an online forum that once the rider reaches his destination, the suitcase will automatically open when the rider leaves the vehicle. But Linley said this didn't happen in this case. After using the Waymo app before, Linley knew that a button in the app would allow passengers to open their suitcases. But this time, Linley said there was no option to open the suitcase through the app, and the suitcase did not open itself.

"So I called customer service to see if anyone could open the car remotely for me," Linley recalled. "A guy picked up the phone and he was very kind, trying to open the suitcase in the middle of him and the car drove away."

"I thought, 'You know the car is driving, I have a picture, I don't know what you want me to do,'" Linley said. "He's very calm and very friendly, he's gone, 'Well, I'll submit a missing report for you.'"

Linley recalls that his items were easily seen through the torso window, so he thought Waymo wouldn't have a hard time finding them. In the trunk of that car, he said, was a large duffel bag full of tennis balls, a portable teaching cart, several "holes", his personal tennis rackets and other gear.

Not only is the lost equipment expensive, he added, he is losing money because there is no lessons without it.

Linley said he has been asking Waymo to return his property or reimburse him for the past two months. But he said that despite dealing with multiple Waymo agents, none of them happened.

This week, Linley filed a small claim lawsuit against Waymo for $12,500. The amount, he said, includes the value of the lack of equipment and the loss of income from the inability to teach. Linley said he currently has more than 20 people asking to attend classes with him, but he has no equipment to help them.

Waymo rejected an interview request from the NBC Bay Area, but a spokesperson said in a statement: "Waymo stays in touch with individuals and works to resolve claims. Waymo's support team aims to reintegrate riders and their forgotten items."

“They were not forgotten,” Linley said of his property.

He insisted: "They got lost, it wasn't my agreement, they weren't lost by me, they were taken away by the car."

Linley was frustrated and confused about where his belongings might have gone.

He said a Waymo representative he contacted told him that the company is still investigating his case.

Linley said, "I thought, 'I don't know what to investigate. Are you printing? Are you calling? What is the FBI going to investigate? What is it going to investigate? Find these things!''

He added that the whole experience made him reconsider whether to move forward with Waymo.

Currently, he has advised other riders: “I want your stuff to be in the back seat, and that’s what I suggest.”
