For the past decade, Uber's annual Lost & Found Index has offered a quirky glimpse into human forgetfulness. From mundane items like smartphones and laptops to more unexpected finds such as live fish and single shoes, this year’s report takes on a new twist with the addition of robotaxis.

Thousands of items have been left behind in these autonomous vehicles, ranging from practical keys and wallets to the decidedly bizarre: dentures, an “I Heart Hot Dads” bag, and a blue hat reading “Emotional Support Human.” This not only highlights the persistent human habit of leaving belongings but also suggests that even in a future where cars drive themselves, someone still must retrieve them.

Uber has spent years partnering with autonomous vehicle (AV) technology companies. It wasn’t until March 2025, when Waymo on Uber began operations in Austin, that the robotaxi service truly took off. Since then, Uber and Waymo have launched a similar service in Atlanta, while adding other AV companies such as Motional and Avride to its app.

Despite these advancements, the thousands of lost items already logged provide insight into how many rides are being completed on Uber’s platform. The process for recovering these items remains straightforward: open the app, select the trip during which the item was left, and contact customer support. Riders can choose between same-day local delivery or picking up their belongings from an AV depot.

As autonomous vehicles continue to scale, Uber is investing in a new business division called Uber Autonomous Solutions, designed to offer a suite of services for operating these vehicles efficiently. With plans to offer robotaxi rides in as many as 15 cities globally by the end of the year and ambitions to be the world’s largest facilitator of AV trips by 2029, it seems humanity is ready to embrace our technologically-assisted forgetfulness.
