A self-driving Waymo taxi sped off with a passenger's belongings still locked in the trunk at a California airport leaving him stranded without clothes, work materials or any clear answers as to how to get them back.
Di Jin said what was supposed to be a routine trip to San Jose International Airport turned into chaos the moment he stepped out of the car.
The businessman from the South Bay near San Francisco had booked his first-ever ride in a driverless cab on Monday.
The journey itself was uneventful but trouble began as soon as the ride ended.
'I pressed the trunk open button, try to get my luggage, but it doesn't do anything, and it drives away immediately,' Jin told NBC Bay Area, describing how the autonomous vehicle made off with his suitcase still inside.
Within seconds, the car along with everything he needed for his trip, was gone.
Jin said he immediately contacted Waymo's customer support, hoping the vehicle could be make a u-turn.
Instead, he was told the robotaxi was already en route back to its depot and could no be stopped.

The ride, operated by Waymo, was otherwise uneventful until the drop-off. Jin said the trunk failed to open when he attempted to retrieve his luggage at the airport

With no time to recover his belongings, Jin boarded his flight to San Diego empty-handed.
'So I have no luggage, no clothes to change, and all my work notes are in my luggage,' he explained.
Hours later, Waymo confirmed that his suitcase had been recovered but what followed only deepened his frustration.
A company representative told Jin: 'While we would love to get this item back to you as quickly as possible, Waymo is unable to cover the cost of shipping labels or courier fees.'
Instead, the company offered him two options: Jin could pay to have his belongings shipped back, or he could use two complimentary Waymo rides to travel to and from a depot to collect them himself - a two-hours round trip journey.
'It sounded terrible. It doesn't make any sense at all, because it's not my mistake,' Jin said.
On its website, the company states it 'is not responsible for items left behind in the vehicle after your trip ends and does not provide refunds or reimbursement for the value of lost items.'
But Jin said that it was no ordinary case.
Waymo offered Jin two complimentary rides to travel to Waymo's depot and retrieve the luggage himself. The round trip to collect his belongings would have taken over two hours

The company says trunks can be opened via a button on the vehicle or through its mobile app
Waymo driverless taxis are widely seen as part of the future of transportation
'I already told them very clearly it's not lost and found, right? I pressed the trunk open button, and it's just not functioning,' he said.
Waymo's own guidance says passengers can open the trunk by using a button on the vehicle or within the app and that it should automatically open when a ride ends.
The incident comes as autonomous vehicles continue to expand into everyday travel.
In November, San Jose became the first commercial airport in California to allow paying passengers to use Waymo's driverless rides.
